About this tour
When Em from our team booked the Kerama Islands snorkelling tour out of Naha, we got a solid seven-hour day on the water with genuine reef time. You're collected from your Naha accommodation, then whisked by speedboat to the Kerama Islands — a protected national park about an hour offshore where the water's genuinely blue and the coral gardens aren't picked over. The outfit runs things fairly tight: guides stick to small groups, hand you quality kit, and the boat crew keeps things moving between snorkel sites. It's pitched at mixed experience levels, so you're not left fumbling alone. Weather and sea state call the shots on where you actually dive each day, which is fair dinkum for this region.
Highlights
- Free pick-up and drop-off within Naha — no extra taxi faff
- Underwater photography service; Em downloaded 2–3 shots same-day
- Complimentary boat coat and wetsuit vest protect against wind
- 4-metre cliff jump option for those keen to launch into blue water
- Hot showers and separate change rooms beat dripping back in a shared space
- Whale-watching added January through March (weather dependent)
- Snorkel kit included; no rental upsell
What to expect
You'll be picked up early from your Naha hotel — expect a 60-minute speedboat ride to the Kerama sites, which isn't a slog because the islands come into view and the sea state is usually calm that far out. Once anchored, guides do a gentle briefing, then you're in the water for three or four separate snorkel dips across the day, with a lunch break midway. The reefs here hold plenty of coral and small reef fish; it's not pristine-wilderness-grade stuff, but it's well-managed national park water so it holds up. Em found the guides attentive without hovering, and the boat crew efficient about managing group transitions. The 4-metre jump is optional and genuinely fun if you're up for it. Downside: you're reliant on weather and swell forecasts — if conditions turn, the operator may shuffle your sites or shorten snorkel time, which is just how open-water tours work in Japan.

Good to know
Pick-up/drop-off from your Naha base saves hassle and cash. The kit's solid and the inclusion of boat coat and insulated vest means you're not shivering between dives in a Okinawa winter wind. Guides are patient with mixed abilities, and the national park status means reefs aren't trashed. Hot showers are a win after a salt-soaked day. Underwater photos downloaded same-day feel generous compared to most.
Full health disclosure is strict — asthma, heart conditions, recent ear surgery, diabetes, and several other conditions may disqualify you, and there's no refund if you fail the health check on the day. You need to bring your own lunch or stump up 980 yen for a bento option. The tour's weather-dependent, so bookings can shift or cancel. Groups aren't tiny (exact size not stated). Early start likely, so late risers should confirm pickup time. Infants must sit on a lap. Peak season (winter whale-watch window) fills fast.
