Why Kerama
If you want Okinawan water the way the postcards promise โ turquoise instead of greenish, with 50 m underwater visibility โ Kerama is the honest answer. The main Okinawa island reefs are mostly degraded or built over; the Kerama islands were made a national park in 2014 and the water quality shows. Zamami is the easiest overnight base; Tokashiki is bigger with more white-sand beaches (Aharen is the headliner); tiny Aka is for day-trippers who like empty swimming coves. Humpback whales also winter here (January-March); dedicated whale-watching boats run from both main islands.

FAQ
- โZamami or Tokashiki? Zamami is nicer for an overnight small-village feel; Tokashiki (Aharen Beach) is slightly closer and better for beach-only day trips.
- โCan I do a day trip from Naha? Yes โ leave Tomari by 09:00 fast ferry, back by 17:00. Snorkel is enough; diving is tight.
- โBest time? April-June and October for warm water + calm seas; Jan-Mar for whales.
- โAny ATMs? Yes on both main islands, but 7-Eleven ATMs do not exist โ plan foreign cash in advance.
- โRental cars? Limited; most Kerama travel is by scooter or bike. Book scooters ahead for Zamami.
- โReef protection? Reef-safe sunscreen is mandatory in some beaches; local shops sell approved brands.
- โSnorkel gear rental? Yes at both ports (~ยฅ1,500/day).
- โSea turtles? Common at Aharen and Nishibama in summer.
- โCombine with mainland Okinawa? Yes โ 2 nights Kerama + 3 nights Naha/Churaumi is a classic 5-night plan.
- โHumpback-watching odds? ~85-90% in January-March; cold water means wet-weather gear even in Okinawa.
