About this tour
When Em from our team booked this full-day dive and snorkel trip to the Kerama Islands, an hour by boat from Naha, we found ourselves in one of Japan's best-preserved marine reserves. The islands, designated a National Marine Park in 2014, host 248 coral species and an impressive lineup of marine life—turtles show up daily, humpback whales arrive each winter to breed, and the underwater scenery shifts with the seasons. The eight-hour experience combines an introductory dive with snorkelling across pristine reefs, all guided by staff who'll tailor the day to what you want to see most.

- Snorkelling and diving in the same day, different depths
- Guides adjust routes based on what you want to spot
- Lunch and towel rental built into the package

What to expect
Em's day began with a pickup from a designated Naha location, then a scenic hour-long boat journey to the Kerama Islands. The crew ran a proper safety briefing before the introductory dive—nothing rushed, and they made sure she felt comfortable with the gear. The water was clear, and the coral coverage was genuinely impressive; guides know the best spots and will pivot to find what you're keen on. You'll spend time underwater, surface for air and a breather, then switch gears into snorkelling mode across shallower reefs where the pace is easier and the light better for spotting things. Lunch was provided mid-day on the boat, which helped break up the rhythm. By afternoon, you're back on the boat heading to Naha. The whole operation felt well-drilled and safety-conscious.

Good to know
If you've never dived before, this is a sensible entry point—you get real gear and real depth without committing to a full certification course. The Kerama Islands are genuinely pristine, with coral and fish stocks that rival much pricier overseas destinations. Combining diving and snorkelling means you get two experiences in one day, and the guides are genuinely responsive to what you want to see. The inclusion of lunch and towel rental removes hidden costs.
This tour requires solid fitness—the operators are clear about that, and they're not wrong. Expect early starts, physical exertion in the water, and a full day. It's not suitable for anyone with spinal issues, cardiovascular concerns, or if you're pregnant. The boat ride can be bumpy, so pack motion sickness meds if you're prone. You'll need to bring your own swimsuit. Group sizes aren't specified, so it could be intimate or busy depending on the day. Peak season (winter, when whales are around) will be more crowded than shoulder months.
