What to Expect on the Day
Departure from Naha port
Kerama Islands tours depart from Naha's Tomari Port or Itoman Port — both in the south of Okinawa's main island. Check-in is typically 30 minutes before departure. The high-speed ferry to the Kerama Islands takes 30–50 minutes depending on conditions. In winter (Jan–Mar), dress in layers for the crossing — the wind chill can make the transfer feel cold even in subtropical temperatures.
Humpback whale watching (January–March)
During January to March, humpback whales are present in the Kerama Island waters as part of their southern migration. Boat captains and guides watch for whale activity during the crossing and in the bays. When humpbacks are spotted, the boat slows and observes from a regulation distance. Surface activity is common in Kerama waters — breaching and pec slapping are frequent. If your visit falls in January–March, a sighting is likely.
Kerama Islands snorkeling
The Kerama Islands (Keramashoto National Park) have some of the clearest water in Asia — Kerama Blue is the local term for the distinctive cobalt-turquoise colour. Snorkeling spots are in sheltered bays with live coral at 2–8 metre depth. Sea turtles are extremely common — encounter on most trips. The coral is densely populated with tropical fish: butterflyfish, parrotfish, angelfish, Moorish idol, and Nemo-clownfish in their anemones.
Whale shark encounter at Yomitan (separate tour)
The whale shark tours (t2 and t4) depart from the Yomitan area on Okinawa's northwest coast — a separate location from the Kerama Islands. Whale sharks are encountered in specific locations where conditions concentrate them. These are docile filter feeders that pose no risk to swimmers — encounters involve swimming alongside or below the whale shark while it moves slowly through the water filtering plankton. Guides ensure safe distances and non-disruptive behaviour.
What to Bring — and What to Leave at Home
✓ Bring
- Swimwear and rash guard — reef protection and UV coverage on the water
- Waterproof bag for phone and camera — spray on boat transfers
- Sunscreen SPF 50+ (reef-safe) — subtropical UV is intense
- Light jacket for early morning departures in winter (Jan–Mar)
- Underwater camera or housing — Kerama visibility makes photography excellent
✗ Leave at home
- Regular chemical sunscreen — Kerama is a national park; reef-safe sunscreen only
- Fins if you rent them from the operator — check inclusions first

How to Choose an Ethical Tour
What ethical operators do
- Use reef-safe sunscreen only — Kerama is a national park with strict reef protection
- Do not touch coral or stand on the reef — one touch kills decades of growth
- Maintain at least 3 metres from sea turtles — no chasing or blocking their path
- For whale sharks: swim parallel, never above — avoid shadowing or blocking their movement
Red flags to avoid
- Chemical sunscreen in Kerama waters — harmful to coral, prohibited in the national park
- Flash photography near humpback whales — disruptive during nursing/breeding season
- Touching whale sharks — never permitted on any responsible tour
