The Ultimate Marine Destination Showdown
For Japanese divers and snorkelers, two destinations dominate the conversation: Palau and Okinawa's outer islands. Both promise crystal-clear waters and spectacular marine life, but they deliver fundamentally different experiences. Palau offers raw, untouched reef systems and pelagic encounters. Okinawa's islands provide convenience, Japanese-language comfort, and surprisingly diverse diving.
I've logged over 200 dives between these two regions, and choosing between them depends entirely on what you want from your underwater time.
Palau: World-Class Diving, Remote Beauty
Palau's Blue Corner is consistently ranked among the world's top 10 dive sites. The reef shark population alone makes it worth the trip. Jellyfish Lake offers a surreal snorkeling experience found nowhere else on Earth. The Rock Islands' UNESCO-listed lagoon system contains over 500 species of coral — more than the entire Caribbean combined.
The downside? Palau requires a connecting flight through Guam or Korea, diving costs are high (US$150-200 per two-tank dive), and accommodation options are limited outside Koror.
Okinawa Outer Islands: Japan's Hidden Reefs
Miyako, Kerama, and Ishigaki islands offer diving quality that rivals anywhere in Southeast Asia. The Kerama Islands are just 30 minutes by fast ferry from Naha, with visibility regularly exceeding 30 meters. Ishigaki's manta ray season (June-November) delivers close encounters with these gentle giants on almost every dive.
The advantage is obvious: domestic flights, Japanese-speaking dive shops, familiar food, and no passport or visa hassle. Dive costs run 10,000-15,000 yen for two-tank boat dives — comparable to Palau when you factor in Palau's travel costs.
Snorkeling Comparison
If you're not a diver, Palau still edges ahead for snorkeling thanks to Jellyfish Lake and the shallow reef systems around Rock Islands. But Okinawa's Kerama beaches offer beach-entry snorkeling with sea turtles that's hard to beat for accessibility. Miyako's Yonaha Maehama beach has some of the clearest nearshore water in all of Japan.
Which Should You Choose?
Choose Palau if: you're an experienced diver seeking world-class pelagic encounters, you don't mind the logistics, and you want bragging rights. Choose Okinawa's outer islands if: you want great diving without the hassle, you're traveling with non-divers who need land activities, or you're learning to dive.
Q: How much does a Palau dive trip cost from Japan?
A: Budget 200,000-300,000 yen for a 5-day trip including flights, accommodation, and 8-10 dives. Okinawa equivalent costs 100,000-150,000 yen.
Q: What's the best season for each destination?
A: Palau is diveable year-round with best visibility November-May. Okinawa's outer islands peak March-October, with manta season June-November at Ishigaki.
Q: Do I need dive certification for either?
A: Yes for most dive sites. Both destinations offer discover scuba experiences for beginners. Get certified at home first to maximize your dive time on the trip.
Q: Is Palau safe for Japanese travelers?
A: Extremely safe. Palau has deep historical ties to Japan. Many locals speak some Japanese, and Japanese signage is common in Koror. The island nation is one of the safest in the Pacific.
Q: Can I combine Palau with another destination?
A: The Guam connection makes a Palau-Guam combination natural. Fly Tokyo-Guam, spend 2 days, then Guam-Palau for 4 days, and return via Guam.
