Let me begin with an honest correction. The earlier version of this page listed Shiretoko, the Sapporo Clock Tower and even Hakone Shrine as "day trips from Hokkaido". That was muddled in three different ways. Hakone is on the main island of Honshu, hundreds of kilometres south, and has nothing to do with Hokkaido. The Clock Tower is a pleasant stop inside Sapporo itself, so it is not a trip at all. And Shiretoko, magnificent as it is, sits at the far north-eastern tip of the island, which makes it an overnight journey rather than a day out. I would rather fix that properly than leave you planning around places that do not fit together, so this is a fresh guide written for travellers who are actually going to be on the ground.
Here is the first thing worth understanding: Hokkaido is not a city, it is an island roughly the size of Austria. When people say "day trips from Hokkaido" they almost always mean day trips from Sapporo, the prefectural capital, or from New Chitose Airport, where most flights land. Sapporo is the natural base because the trains, the highway buses and the organised day tours all radiate out from it. From there you can reach a canal town, a volcanic hot-spring valley, a caldera lake, a zoo, a flower-and-hills landscape and a few quieter surprises, all in a single day and all back in your bed by night.
I have organised this guide the way I would explain it to a friend flying out of Singapore. First, how the island works and how to move around. Then the trips that genuinely work as day outings, one by one, with realistic timings. Then the places people badly want to see but that deserve more than a day. After that come the seasons, a few tables to help you compare options, a sensible budget, and a section on getting there from Singapore and what to sort out before you fly. Read the parts you need; skip the rest.
How Hokkaido really works for day trips
If you are used to Singapore, where nothing is more than an hour away, Hokkaido takes some mental adjustment. Distances are large, the weather decides a surprising amount, and public transport is excellent on the main corridors but thin elsewhere. The good news is that the main corridors happen to be exactly where the best day trips are.
Sapporo sits roughly in the middle of the western half of the island. The airport at Chitose is about forty minutes away by train. West along the coast is Otaru. South-west, along the Pacific side, are Noboribetsu and the lake country around Toya and Shikotsu. North-east, the line runs towards Asahikawa, Biei and Furano. Hakodate, the old port city, is at the southern tip and closer to four hours away by express train, which pushes it out of day-trip territory unless you really enjoy trains. Everything past that, Lake Akan, Kushiro, Abashiri, Shiretoko, Wakkanai, belongs to a different kind of trip.
There are broadly three ways to do a day trip, and your choice shapes the day more than the destination does.
- By train on your own. Cheapest and most flexible on the Otaru, Noboribetsu and Furano lines. You decide when to stop for lunch. The catch is the last mile: a station near a lake or a zoo is often still a bus ride from the actual sight, and bus times thin out quickly in the afternoon.
- By organised day tour from Sapporo. A coach picks you up in the city, stitches three or four stops together and brings you back. You lose spontaneity but you gain an enormous amount of time, because a good itinerary links places that would take you two awkward transfers each by public transport. In winter this is, frankly, the most relaxing option.
- By rental car. Wonderful in summer if you are comfortable with left-hand driving and have an international licence in order. In winter I would not recommend it to anyone who has never driven on snow and ice. Roads can be white-knuckle even for locals.
One more point on cash. The old page said to bring cash because rural places do not accept cards, and that is partly true. Big attractions, stations and chain restaurants take cards and transport IC cards without fuss, but small ramen shops, market stalls, some bus operators and a few onsen entrances still prefer notes and coins. Keep a few thousand yen in your pocket and you will never feel stuck.
Otaru: the canal town that is easiest to love
If you only do one day trip from Sapporo, make it Otaru. It is the easiest, the prettiest and the most forgiving of bad weather. The rapid train from Sapporo takes about thirty to forty minutes, much of it with the sea on one side of the window, and trains run frequently enough that you never need to plan around a timetable. You can leave after a late breakfast and still be back for dinner in Sapporo.
Otaru was once the commercial heart of Hokkaido, a herring-and-trade port with banks, warehouses and shipping offices that rivalled anything in the country. When the economy moved on, the stone buildings stayed. The famous canal, lined with old brick warehouses and gas-style lamps, is what most people come to photograph, and it is lovely in any light. But the pleasure of Otaru is the wandering. Walk the canal, then climb away from it, and you find sloping streets, small museums and glass workshops that reward an unhurried afternoon.
There are three things I would build the day around besides the canal itself:
- The art and architecture quarter. Two buildings in particular are worth your time. One is a 1923 former bank, now a museum with a magnificent high-ceilinged hall, and the other is a stained-glass museum in a pair of historic warehouses. Both are on the same walk and both are indoors, which makes them a perfect plan B when the weather turns.
- Mount Tengu and its ropeway. A short cable car carries you up to a viewpoint over the town, Ishikari Bay and, on a clear evening, a glittering night view. The summit also has a small folklore museum about the long-nosed Tengu goblin, which children tend to enjoy more than they expect.
- Food. Otaru is a seafood town. Sushi counters here are unusually good value compared with Tokyo, and the local sweets shops are an easy way to feed a group of cousins.
The art museum in the old bank is on offer as a foreigner-only ticket, with entry from about S$10.00, and you can read the details here: Nitori Museum of Art in Otaru. The stained-glass museum is sold the same way, from about S$10.00: Stained Glass Museum in Otaru. Both are collected at the same ticket gate, so you can do them back to back without any walking in between. If you would rather go up the hill, the ropeway ticket is from about S$15.57: Otaru Tenguyama.
Timing matters here. In summer the museums open at half past nine; in the colder months they open a little later and close on Wednesdays. For the stained glass specifically, an afternoon visit on a sunny day is when the colours project best onto the floor. If you want the night view from the mountain, add a couple of hours and be prepared to come back to Sapporo a bit later than usual. Otaru in winter, with snow along the canal and small candles set out in the evenings during the snow-light festival in February, is the most romantic place I know on the island.
Noboribetsu: steam, sulphur and a surprisingly good aquarium
Noboribetsu is the second pillar of the Sapporo day trip. It is the most famous hot-spring town in Hokkaido, and the reason is Jigokudani, the Hell Valley, a crater-side landscape of steaming vents, yellow rock and bubbling streams that feeds the onsen below. The limited express from Sapporo takes a little over an hour, then a short bus climbs from the station to the spa town. On a cold morning the steam rising from the valley is genuinely dramatic, and the smell of sulphur tells you immediately that you are standing on something alive.
A walk along the boardwalks through the valley takes about an hour if you stop for photographs. A longer path continues into the hills towards a set of smaller ponds, but you do not need it. The ordinary visit gives you the main show. After that you have two sensible choices. Soak in one of the onsen hotels that sell day-use bathing, or head down to the coast for the marine park, where an aquarium built like a European castle runs dolphin and sea lion shows that suit families with small children. Plan on two to three hours there, and note that admission closes about half an hour before the park does. Tickets are from about S$27.67: Noboribetsu Marine Park Nixe.
I would be straightforward about one thing. If you do Noboribetsu by train alone, it is a satisfying half-day but not much more, and the transfers between the valley, the town and the coast eat time. This is where an organised tour pays for itself. A popular combination bundles Noboribetsu, Lake Toya and Otaru in a single long panoramic day of roughly ten to twelve hours from Sapporo, and the price works out cheaper than paying for three separate train-and-bus legs. It is from about S$69.43: Hokkaido Noboribetsu, Lake Toya and Otaru panoramic day tour. Be at the meeting point at least ten minutes early; late arrivals cannot join.
In winter there is a variation on this theme that links Hell Valley, Lake Toya, a bear ranch at Showa Shinzan and the Lake Shikotsu ice festival, an event in which thousands of frozen lantern-like sculptures glow after dark. It runs only in the coldest weeks, typically late January to mid-February. Reservations close by ten in the morning the day before, so do not leave it to the last minute: Noboribetsu Jigokudani, Lake Toya, Showa Shinzan and Lake Shikotsu winter day tour, from about S$78.76.
Lake Toya: a caldera you can circle in a day
Lake Toya is the quietest of the big sights near Sapporo, and I mean that as a compliment. It is a near-circular caldera lake with a green island in the middle, a volcano, Usu, smoking on its southern shore and the shapely cone of Mount Yotei visible across the water on clear days. It takes just under two hours by train and bus from Sapporo, which is why it works best as part of a bigger loop with Noboribetsu rather than a standalone trip.
The main activity is a sightseeing boat to Nakajima island, a forested spot in the middle of the lake where deer wander around and walking trails take you through the trees. The boat is a leisurely ride, and the trip as a whole needs two to three hours if you include the walk. Early morning and late afternoon give the best light on the water. In October the autumn colour around the shore is spectacular, and in July and August the lake is the setting for a nightly fireworks display over the water that locals love. Tickets for the Nakajima cruise are from about S$15.00: Lake Toya sightseeing cruise to Nakajima.
A tip I learned the slow way. Because Lake Toya is the middle stop of the south-western loop, it is tempting to try to see everything with just an hour here. Resist that. If you are on a coach tour, that hour is fine for the viewpoint and a coffee. If you are on your own, give yourself a proper afternoon, or be prepared to feel that you merely drove past one of the island's loveliest places.
Biei, Furano and the Asahiyama Zoo
North-east of Sapporo, the landscape shifts from coast and volcano to rolling farmland, patchwork hills and wide skies. The towns of Biei and Furano are the heart of it. Their reputation rests on summer lavender fields and flower-striped slopes, but the area is no less photogenic in winter, when the hills turn into smooth white curves under a pale blue sky.
The trouble is distance. Furano is around two hours from Sapporo by train, and Biei and Asahikawa lie further along the line. Many travellers try to squeeze the area into a day and spend more of it in transit than anywhere else. A guided day trip that picks you up in Sapporo solves most of that. One of the most popular combines the Asahiyama Zoo in Asahikawa, famous for its penguin walks in winter and for letting you see animals from unusual angles, with the Blue Pond near Biei and a snowy forest terrace in Furano. The tour takes ten to eleven hours, and if the zoo happens to be closed that day the guides swap in extra scenery in Biei and Furano. It is from about S$69.43: Asahiyama Zoo, Biei Blue Pond and Terrace day trip.
If you prefer your own pace and are in Hokkaido for several days, the regional rail passes can make the economics work. A four-day Sapporo and Furano area pass covers the trains between the two plus a good number of local lines, from about S$95.06: JR Hokkaido Sapporo-Furano Area Pass. Check the delivery and eligibility details on the product page before you buy, since some versions are limited to travellers in particular countries. Peak lavender season is July and the first days of August; if you are visiting then, book accommodation early because Furano's few small hotels fill quickly.
Chitose and Tomakomai: the easy trips next to the airport
Most visitors landing at New Chitose skip the area entirely and head for Sapporo. That is a pity, because the corridor between the airport and Tomakomai has a handful of excellent family stops that are easy to combine on your arrival or departure day when you do not want to be too far from the terminal.
The Chitose Salmon Aquarium is a genuinely unusual place. It is built around a river, and its signature exhibit is an underwater window into the river itself, so you can watch salmon swim upstream from below. It is indoors, takes about an hour to an hour and a half, and makes sense on a wet or windy day. The best season for the spawning run is roughly September to November. Tickets are from about S$8.00: Chitose Salmon Aquarium.
Further down the line, Northern Horse Park near Tomakomai is the place for families who like animals more than museums. You can feed and pat horses, take a guided ride across the fields and, in the snowy months, try activities that take advantage of the winter landscape. A free shuttle runs for guests, and you swap your e-ticket for a printed one at the front desk, so go to the desk first. Tickets are from about S$20.00: Northern Horse Park. It makes a good half-day, and it is one of the few Hokkaido outings that works equally well for grandparents and toddlers.
Hakodate: worth it only with the right plan
I get asked about Hakodate more than any other place, so let me be straightforward. It is a beautiful port city. The harbour, the old western-style district on the slopes, the night view from Mount Hakodate and the morning fish market deserve their fame. It is also about three and a half to four hours by express train from Sapporo, each way. As a day trip that is seven or eight hours of sitting for a few hours of sightseeing, and I would not do it unless you absolutely must.
What I would do instead is treat Hakodate as an overnight. Take a morning train, drop your bags, walk the old district in the afternoon, see the night view from the mountain, have a late sushi dinner, then spend the following morning at the market and at Goryokaku. That star-shaped fort, built in the nineteenth century and now surrounded by a garden, is one of the great spring cherry-blossom sites in northern Japan, with a tower observation deck that shows the star shape clearly. Late April to early May is the time for blossom, and late October for autumn colour. It is open from early morning and takes two to three hours: Goryokaku Garden and Tower, from about S$10.00.
If you are travelling extensively through the south of the island and into the northern part of the main island of Honshu, the six-day South Hokkaido and Tohoku rail pass might be worth a look, from about S$275.56: JR Tohoku-South Hokkaido Rail Pass. It only pays off if you will be riding the Shinkansen and limited expresses often, so add up the individual fares first.
The big ones that need more than a day: Akan, Shiretoko and beyond
The old page led with Shiretoko Peninsula National Park, and I understand why: it is one of the most extraordinary wilderness areas in Japan, a World Heritage Site where brown bears, sea eagles and drifting winter ice come together in one remote peninsula. But Shiretoko is on the far eastern side of the island, many hours from Sapporo. The honest way to see it is to fly to Memanbetsu or Nakashibetsu airport, base yourself in a small town such as Utoro or Rausu for a couple of nights, and take a boat or guided walk. It is a trip in its own right and worth planning that way.
Lake Akan is similar. It sits in the Akan-Mashu National Park in the east, around five hours from Sapporo by road or a mix of train and bus. The lake is known for its marimo, the rare green algae balls, and for an Ainu village on its shore where you can learn about the island's indigenous culture. A seventy-minute sightseeing cruise includes a stop at an observation centre where marimo are kept; tickets are from about S$13.00: Lake Akan cruise and marimo observation centre. In the evening the forest hosts Kamui Lumina, a one-kilometre night walk of projection mapping and light installations based on Ainu legends. It uses a rhythm staff that lights up as you go, takes about an hour and runs in time slots that change through the season: Lake Akan Forest Night Walk Kamui Lumina, from about S$41.52.
Put those two together, an afternoon cruise and a night walk, and Akan makes an ideal overnight. Do not try to do it as a day trip from Sapporo. You will spend your whole day in a vehicle, then arrive just in time to see the last slot sell out.
Winter day trips: skiing, snow festivals and sensible expectations
For many visitors from Singapore, winter in Hokkaido is the dream: real snow, steaming outdoor baths and the chance to ski for the first time. A day trip works well here because Sapporo has several ski areas within an hour or so, and some of them are set up specifically for beginners who have never put on skis.
One resort near Otaru combines gentle beginner slopes with a view of the sea, and operators offer day packages with lessons in English or Chinese, equipment and transport from Sapporo. It is open in the main winter season, with limited weekday hours in the quieter weeks. It is from about S$45.90: Asarigawa Onsen ski resort day trip. If you have never skied, take the lesson. The first two hours are humbling, the next two are fun, and you will not regret having an instructor who speaks your language.
A few honest notes about winter. Daylight is short, with the sun setting around four in the afternoon in December, so a day trip that looks long on paper is shorter in practice. Trains can be delayed or cancelled in heavy snow, and tours sometimes alter their route. Dress in layers, with a proper waterproof outer, gloves and a hat. Grippy soles matter more than anything else you pack, because pavements that look dry can hide a thin film of ice. And build some slack into your final day. Nothing spoils a trip like running for a flight after a snowed-in morning.
Comparing the day trips side by side
These tables are my rough working figures for planning. Times are approximate and depend on the season, the connections and the traffic, so treat them as a guide to the shape of each day rather than a promise.
| Destination | From Sapporo | Good for | Works as a day trip? |
|---|---|---|---|
| Otaru | About 35 minutes by rapid train | Canal, museums, seafood, night view | Yes, the easiest |
| Noboribetsu | About 75 minutes by limited express | Hell Valley, onsen, marine park | Yes |
| Lake Toya | About 2 hours by train and bus | Cruise, volcano views, fireworks in summer | Yes, best combined with Noboribetsu |
| Biei and Furano | About 2 to 2.5 hours | Lavender, hills, Blue Pond, zoo | Yes, with a tour |
| Chitose and Tomakomai | 40 to 70 minutes | Aquarium, horses, airport days | Yes, short |
| Hakodate | About 3.5 to 4 hours | Port, night view, Goryokaku | Only as an overnight |
| Lake Akan | About 5 hours | Marimo, Ainu culture, Kamui Lumina | No, stay overnight |
| Shiretoko | Many hours, usually via a flight east | Wildlife, wilderness, drift ice | No, 2 to 3 nights |
And here is how I would match a trip to the kind of traveller you are:
| If you are... | Choose | Why |
|---|---|---|
| A first-time visitor with one free day | Otaru | Close, flexible, great in any weather |
| Travelling with young children | Noboribetsu Marine Park, Chitose Aquarium, Northern Horse Park | Animals, shows, short travel times |
| With older parents | A coach day tour to the lake country | No transfers, seat reserved, little walking |
| A photographer in summer | Furano and Biei | Lavender and layered hills at golden hour |
| A first-time skier | Beginner slopes near Otaru | Lessons in your language, easy transport |
| A history and architecture fan | Otaru museums, then an overnight in Hakodate | Old banks, warehouses and forts |
When to go: what each season offers
Hokkaido has four distinct seasons, and your trip will feel quite different depending on which one you choose. Singaporeans tend to think of it as a winter destination, but the summer is arguably the easiest time to travel, while the shoulder months are often the quietest.
| Season | What you get | Watch out for |
|---|---|---|
| Spring (April to May) | Cherry blossom arrives late, around late April to early May; fresh green hills | Melting snow, muddy trails, some mountain roads still closed |
| Summer (June to August) | Lavender in July, mild temperatures, lake cruises, long daylight | Busy weekends, early sell-out of hotels in Furano |
| Autumn (September to November) | Vivid foliage, salmon runs, harvest food | Cold evenings, shorter days by November |
| Winter (December to March) | Powder snow, ice festivals, penguin walks, hot-spring soaks | Delays, icy pavements, sunset before 4:30 pm |
If I had to choose a single month for a first trip, I would say late September or early October. The crowds drop, the air is crisp and the foliage in the lake country is at its best. For snow, February is the heart of the season, and for lavender, mid-July.
Moving around: trains, passes and tours
The question I hear most often is whether a rail pass is worth it. The honest answer is that it depends on how much you travel. Individual tickets on the Otaru line are inexpensive, so a pass will not pay for itself on one short trip. Passes become attractive when you plan several longer legs, such as Sapporo to Furano and back, plus Noboribetsu, plus an excursion to the south. Tally your intended trips against the pass price before you decide.
The full network pass, which covers unlimited travel on JR Hokkaido trains and some buses for a fixed number of days, is the one for people who want freedom across the island. Check the delivery and eligibility conditions, because some versions are sold only in certain countries. The version listed here is from about S$187.78: JR Hokkaido Rail Pass. If your plans are modest, a regional pass or simple IC card top-ups will be cheaper.
Another option worth knowing is a multi-attraction pass. One weekly pass gives you access to a set number of facilities of your choice across the island over seven consecutive days. It suits travellers who like variety and do not mind choosing in advance, and it helps with budgeting because you know your entry costs up front: Have Fun in Hokkaido pass, from about S$37.00. Remember that some venues require advance reservations, and opening hours can change with the season, so read the participating list before you plan around it.
Whatever you choose, get a rechargeable IC transport card on arrival. It works on trains, subways and many buses across Sapporo and beyond, and saves you from hunting for coins at ticket machines.
A sample three-day plan from Sapporo
If you have only a few days and want to use Sapporo as a base, here is how I would arrange things so that no day is wasted and nobody is exhausted.
| Day | Plan | Pace |
|---|---|---|
| Day 1 | Arrive at Chitose, settle into Sapporo, evening stroll and a bowl of local ramen | Easy |
| Day 2 | Otaru by train: canal, two museums, seafood lunch, Mount Tengu at dusk | Moderate |
| Day 3 | Coach tour to Noboribetsu and Lake Toya, or Biei and Furano in season | Full day |
| Day 4 (optional) | Chitose aquarium or Northern Horse Park on the way back to the airport | Light |
What I like about this shape is that the easy trip comes first, while you are still adjusting to the cold and the time zone, and the long coach day comes when you feel settled. The last day deliberately stays close to the airport, because nobody enjoys a two-hour transfer on the morning of a flight.
What it costs: a realistic day-trip budget
Prices in Japan are often lower than Singaporeans expect, especially when the yen is weak, but they add up. Here is a rough guide to what a day out costs per adult, excluding accommodation. Treat the amounts as ballpark figures and check current prices before you commit.
| Item | Typical range | Notes |
|---|---|---|
| Return train to Otaru | Roughly S$15 to S$20 | Frequent rapid service |
| Museum or ropeway entry | About S$10 to S$16 each | Check season hours |
| Seafood lunch | S$20 to S$45 | Sushi counters vary widely |
| Full-day coach tour | About S$70 to S$80 | Transport and guide included, lunch usually extra |
| Aquarium or animal park | About S$8 to S$30 | Cheaper for children |
| Beginner ski day with lesson | About S$45 and up | Gear hire may be extra |
Two budget habits have saved me real money. First, eat your main meal at lunch, when set menus are often a third cheaper than at dinner. Second, buy attraction tickets before you go, so that you are not tempted by walk-up prices or caught out by a sold-out time slot.
Getting there from Singapore and sorting out the paperwork
There is rarely a nonstop service from Singapore to Hokkaido all year round, so most travellers connect through a hub in Japan or elsewhere in Asia. Schedules change from season to season, so check the current options when you are ready to book. Allow for a full travel day each way and do not plan anything demanding on the day you arrive.
On the visa side, Singapore passport holders can visit Japan for short tourism stays of up to ninety days without applying for a visa in advance, according to the current official information. Rules differ by nationality, so if you are travelling with relatives or friends who hold other passports, check what applies to them. Our visa requirements guide lets you look up your own passport and see the entry options for Japan in one place. Whatever your nationality, register for the online arrival system before you fly, as it speeds up immigration and customs.
One practical point that catches people out. If your nationality requires a visa and the application asks for proof of onward travel or an itinerary, a booked ticket is not always necessary at that stage, and committing to a non-refundable fare before the visa is approved is a risk. For that situation we offer a flight reservation service. To be clear about what it is: it is a manual reservation used to support a visa application, not an issued ticket, and it does not guarantee approval. It simply spares you from paying for a full fare you might never use.
Before you leave, pack for the weather you will really face, not the weather you hope for. Even in summer the evenings can be cool, and in winter the cold is serious. Bring a data eSIM or pocket Wi-Fi so you can use maps and translation apps on the road, notify your bank of your travel dates, and take out travel insurance that covers winter sports if you plan to ski.
Etiquette and small things that make trips smoother
A handful of habits will make your day trips more pleasant for you and for the people you meet.
- Onsen manners. Wash thoroughly before entering the bath, keep towels out of the water, and check the venue's policy on tattoos, which varies from place to place.
- Wildlife. Hokkaido has foxes, deer and, in the wilder parts, brown bears. Never feed animals, keep your distance, and follow the signs and any bear-bell advice on forest trails.
- Ainu culture. At Ainu sites, be respectful and ask before photographing people up close. Visiting a cultural centre is one of the best ways to understand the island's history beyond the postcard views.
- Rubbish. Bins are scarce in Japan, so carry a small bag and take your rubbish with you until you find a proper place to put it.
- Quiet transport. Keep phone calls and loud conversation off trains and buses.

Frequently asked questions
What is the best day trip from Sapporo for a first visit?
Otaru. It is about half an hour away by train, has plenty to do indoors and out, and does not require a long day. If you have a second day, add Noboribetsu and Lake Toya on a coach tour.
Can I visit Shiretoko or Lake Akan as a day trip?
Not sensibly. Both are in the eastern part of the island and need an overnight stay, with Shiretoko usually needing two or three nights. They are wonderful, but plan them as separate trips.
Is a day tour better than going by train?
For a single easy destination such as Otaru, the train is better. For multi-stop days, such as Noboribetsu, Lake Toya and Otaru together, or for Biei and Furano, a tour usually saves hours and avoids awkward bus connections, especially in winter.
Do I need a rental car?
Not for the main routes near Sapporo. A car helps in summer in areas such as Furano and Biei if you are an experienced driver with the right licence. I would avoid driving on snow and ice if you have never done it.
When is the best time to see lavender?
Usually early to mid July in the Furano and Biei area, though it varies year to year with the weather. Book accommodation early for that period.
Do Singapore passport holders need a visa for Hokkaido?
For tourism, Singapore passport holders can currently enter Japan visa-free for up to ninety days. Rules change and differ by nationality, so confirm with our visa requirements page before you travel.
Should I carry cash?
Yes, a little. Cards and IC cards work at most major sights, stations and chain stores, but small restaurants, stalls and some local buses prefer cash.
Is Hakodate possible in a day from Sapporo?
Technically yes, but you will spend seven or eight hours on trains. It is far better as an overnight stay, so you can see the night view and the morning market without rushing.
If you take only one piece of advice from all this, let it be to pick fewer places and see them properly. Hokkaido rewards a slow day far more than a crowded checklist, and the island will still be there for your next visit.
