Zamami Island Day Trip.
Ferry out to the Keramas for a day of e-bikes, island soba, and snorkelling the clearest water in Okinawa. Turtles all but guaranteed.
A full day in the Kerama Islands, handled end to end. You'll cross by high-speed ferry to maximise island time, cycle Zamami's coast to viewpoints over the famous Kerama blue, eat a bowl of island-grown mozuku soba, then spend the afternoon snorkelling reefs where sea turtles are close to a sure thing — home to Naha by evening.
The day.

High-speed ferry to Zamami
The fast crossing to the Keramas — around an hour, with the water getting bluer the whole way.

E-bikes & island viewpoints
Pick up e-bikes at the port and ride Zamami's coast to a handful of the island's best lookouts over the Kerama blue and the outer islands.

Island lunch
A bowl of locally grown mozuku soba. Prefer something else? We can usually sort it.

Snorkel the Keramas
Out on the boat to the day's best reefs around Zamami, Aka, and Tokashiki. Around 90 minutes in the water — turtles almost guaranteed, manta rays in season. chip: Sea turtles · Manta (seasonal)
- 15:30
Rinse off, footage & the port
Shower and change, collect your snorkel footage, then browse the port market and the coral exhibition over a coffee or tea in the air-con.
- 17:20
Ferry back to Naha
The fast boat home across the blue.
- 18:00
Arrive Tomari
Back where you started.
The crossing sets the tone. Fifty-odd minutes out of Tomari on the high-speed ferry and the water starts turning that particular Kerama blue you've probably seen in photos and assumed was edited. It isn't. From the port on Zamami we swap to e-bikes and ride the coast road up to a run of viewpoints looking out over the other islands — Aka, Geruma, Tokashiki floating in the haze — with the whole archipelago spread out below.
Lunch is a bowl of mozuku soba, made with seaweed grown in the water you've been looking at all morning. Then the best part of the day: out on the boat to snorkel the reefs around Zamami, Aka, and Tokashiki, wherever the sea's behaving best that afternoon. Our captain has been running these waters for years and puts your odds of seeing a sea turtle at about 99%. In the right season, manta rays too — in the ocean, nothings guarenteed, but they come through.
Once you're back and rinsed off, there's no rush to the ferry. We pull the footage from your snorkel to your phone, wander the little port market — hand-worked sea jewellery, island tees, the sort of thing you actually keep — and duck into Zamami's coral exhibition, a cool, quiet room to read up on what lives here, above and below the water, over a coffee or tea. Then the ferry home, back in Naha by six.

Full payment due at booking to secure your ferry, bikes, and snorkel reservations. For bookings over ￥100k, we can accept a 20% deposit and the remaining 80% 30 days prior to the tour date.
Full refund if you cancel up to 48h hours prior. No refund if less than 48 hours. If the snorkel is called off due to the weather, we can either offer more view points and beach time, or cancel the tour and offer a 100% refund.
The Keramas can eat a whole day if you let them. We've built this one so you get the best of the water and the island without a single ferry ticket or bike rental to sort yourself. Come ready to get wet..

Super visite d’Okinawa avec une guide enthousiaste et passionnée. Tout était très bien organisé et les explications étaient très intéressantes. J’ai particulièrement aimé la baignade à la cascade. Une très belle expérience que je recommande vivement !
We recently completed the 3-Day 2-Night Northern Okinawa Experience with Evertrail Tours Japan and it was one of the best travel experiences we have had in Japan. This was not a tourist package. It was a genuine adventure into the wild heart of Okinawa and gave us access to places and experiences we would never have found ourselves. From the start, the organisation and hospitality were excellent. We were met at our hotel on the first day by Yumi and taken on our first river trek through beautiful untouched scenery. Due to wet weather, the team proactively offered multiple alternative activities rather than simply cancelling plans. We chose to visit a real Karate dojo where we were introduced to Okinawan Karate training by Karate Master Matsuda-san, who genuinely felt like a real-life Mr Miyagi. It became one of the highlights of the trip. The adventure side of the tour was outstanding. We spent a full day river trekking through jungle landscapes, climbing waterfalls, jumping into crystal-clear pools, and abseiling down waterfalls. The guides balanced safety and excitement perfectly throughout. The accommodation and food were also exceptional. After the trekking day we stayed at a wonderful mountain lodge and enjoyed authentic home-cooked Japanese cuisine using fresh local ingredients. It felt personal and completely unlike a standard hotel experience. Our final day with Aya explored the history of the local caves that sheltered hundreds of people during the war. It added an emotional and deeply human perspective to Okinawa that most visitors never see. Overall, this was a fabulous experience and gave us a genuine connection to the real Okinawa, its nature, history, culture, and people. Highly recommended for anyone wanting something authentic, adventurous, and unforgettable.
Had an amazing time!!
