Tonaki Island

Tonaki island is the island located 60kms off the westcoast of Okinawa mainland.

There are 3 dives sites there and you will see millions of colourful fishes and butterfly fishes by the steep drop-off, explore the underwater cave called "Blue Hole", and spot possibly around 20 green turtles. It is simply one of the best dive sites you can do a day trip from Okinawa mainland. 

We go there several times during the summer.
