Ishigaki is the gateway to Okinawa's southern islands, with its own ring of turquoise bays and coral reefs that rival anywhere in Japan for snorkelling and diving. Kabira Bay's glass-bottom boats glide over vivid coral gardens, while the island's interior of mangroves and pineapple farms gives way to ferry connections to even smaller, quieter islands nearby.

Traveler reviews

★★★★★

Kabira Bay was every bit as beautiful as the photos, and snorkelling at Yonehara afterwards gave us close encounters with huge schools of fish over the coral.

Yui M. · May 2024

★★★★★

Did a manta ray dive that was one of the best diving experiences of my life, then spent the rest of the trip island-hopping by ferry to Taketomi and Iriomote.

Dan R. · October 2023

★★★★☆

Rented a car and drove around the whole island in a couple of days - beautiful beaches everywhere, though it got busy with local tourists during the long weekend we visited.
