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.

Meet at Tomari Port
Gather at the Tomarin ferry terminal in Naha. Quick hello, tickets sorted, and onto the boat.

High-speed ferry to Zamami
The fast crossing to the Keramas — around an hour, with the water getting bluer the whole way.
- 10:00
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.
- 12:00
Island lunch
A bowl of locally grown mozuku soba. Prefer something else? We can usually sort it.
- 13:30
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.
The practical bits.

- Sea life: our captain sees turtles on roughly 99% of trips. Manta rays are seasonal and never guaranteed.
- Weather: snorkel sites around Zamami, Aka, and Tokashiki are chosen on the day for the best conditions, and the sea portion can shift or reschedule for wind or swell.

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..

Moment incroyable, Yumi nous a partagé son savoir et fait découvrir des endroits incroyables que nous n’aurions jamais trouver seule. Merci !🤩 …
My husband and I booked the tour with Things To Do Japan from 3-5 Feb 2026 (culture and coast tour). It was our first time in Okinawa and we were looking to experience Okinawa through the eyes of a local! Aya was our guide and she felt more like a good friend showing us around her beautiful Okinawan island home. Throughout the trip, she shared with us insights and stories not just about Okinawan history and culture, but also about her personal connection to Okinawa (which made the journey all the more personable and memorable! There's a saying that people make the place and we really loved how Aya embodied that with her passion for this island) Beyond exploring various breathtaking local hideaway spots, Aya's sincerity and hospitality made this trip to Okinawa worthwhile! Water boots etc were provided for water activities and we especially loved the spontaneous roadside stop for local fruits! On our last day there, we requested if it would be possible for transport to be arranged to drop us off at the airport and we were glad that Things To Do Japan were able to accommodate this request. Would recommend this company especially if you are tight on time planning your own trip to Okinawa and want a peace of mind Thank you Aya and David for a memorable first trip to Okinawa! <3
This tour was exactly what I needed, calm, beautiful, and perfectly paced. The guides David and Aya really helped me see the beauty of Okinawa and make connections with locals along the way.
