Blue Cave in Onna Village, Okinawa | Choose Diving or Snorkeling on a 2-Hour Tour

What is the Blue Cave?

The Blue Cave is a sea cave off the coast of Onna Village on Okinawa's main island, famous for the way sunlight streaming in illuminates the water with a brilliant blue glow. It may seem dark right after entering, but once your eyes adjust, you'll find yourself surrounded by a space filled with blue light.

The water inside the cave is calm, making it a comfortable environment even for those who aren't used to the ocean. Tours are conducted in small groups, with support available in both English and Japanese.

Choose Between Diving and Snorkeling

This tour lets you choose between a trial scuba dive or snorkeling. Snorkeling is available for participants aged 5 and up, while diving is open to those aged 10 and up, making it easy for families to join together.

A certified guide will be on hand to offer advice and ensure everyone's safety, so the experience is easy to follow even for first-timers. Age requirements differ depending on which activity you choose, so be sure to check the ages of everyone in your group beforehand.

Marine Life and Underwater Highlights

Around the cave, you can get an up-close look at popular tropical fish, including clownfish. Angelfish and eagle rays are also among the creatures you might encounter.

The tour page mentions underwater photography and a fish-feeding experience as part of the offering. Since the specific inclusions vary by plan, it's a good idea to double-check the details on the booking page.
