Rediscover the Underwater world

Have you ever dived into complete darkness?
Aka island is 40 kilometers away from Okinawa Main Island.
With no city lights nearby, the ocean is pitch black at night.

Let’s find sleeping fish and nocturnal creatures such as squids, shrimps, and sharks!

  • Golden Night diving: Every Friday from May to September
  • Coral spawning night diving: 2024: 5/20 to 5/30, 6/19~6/29*
