Yokosuka: Boat Trip to Natural Island and Naval Port Cruise Day Tours

Must Do Experiences

• Board the Yokosuka Naval Port Cruise to see impressive Japanese and American warships up close.

• Explore the mysterious brick ruins and lush forest trails of Sarushima Island, Tokyo Bay's only natural island.

• Savor fresh local seafood and the famous Yokosuka Navy Curry at the bustling Port Market.

Hidden Gems

• Look out for the hidden observation decks on Sarushima Island that offer panoramic views of Tokyo Bay and Mount Fuji on clear days.

• Try the local Yokosuka Navy Burger at the Port Market, a culinary tradition passed down from the US Navy.

• Keep an eye out for the historic French-style brick gun batteries hidden within the dense vegetation of Sarushima.

What Makes it Special

• Offers a rare dual experience of active modern naval fleets and historic abandoned island ruins in one day.

• Includes exclusive insights from a licensed local guide who brings Yokosuka's unique Japanese-American maritime heritage to life.

• Features a visit to Sarushima, an uninhabited natural island often compared to the floating castle in Studio Ghibli's Laputa.

Perfect Timing

When to visit for the best experience

The best time to visit is during the spring (April to May) and autumn (September to November) when the weather is mild and clear, offering the best visibility for the cruise and island exploration. Summer is also popular for beach activities on Sarushima, but it can be quite hot and humid.

Photography Guide

Capture the perfect shots

• Use a zoom lens during the naval port cruise to capture detailed shots of the impressive warships and submarines.

• Take advantage of the dappled sunlight filtering through the trees onto the red brick tunnels of Sarushima for moody, atmospheric photos.

• Head to the upper deck of the cruise ship for unobstructed, wide-angle shots of the Yokosuka coastline.

Cultural Etiquette

Respect local customs and traditions

When photographing naval vessels, follow your guide's instructions, as there may be restricted areas where photography is discouraged. At the Port Market, it is polite to eat your food at designated seating areas rather than walking around while eating. Remember to dispose of your trash in the correct recycling bins, as Japan has strict waste sorting rules.

Special Events & Experiences

Enhanced experiences and seasonal highlights

• Yokosuka Spring Festival in late March, featuring cherry blossoms and naval base open house events.

• Sarushima Ocean BBQ season in the summer, where locals flock to the island for beachside grilling.

• Yokosuka Kaikoku Festival in August, celebrating the opening of the port with spectacular fireworks over the water.

Important Guidelines & Safety

Essential safety information and guidelines

• Stay behind the railings on the cruise ship and hold onto handrails when moving around the deck, especially if the water is choppy.

• Stick to the marked trails on Sarushima Island to avoid steep drop-offs and protect the local flora.

• Stay hydrated and apply sunscreen, as both the boat ride and island exploration offer limited shade.
