A new program for long-stay guests will be held during the Ogasawara Maru’s sailing season!

This is a night-time baby turtle release program, limited to 10 people per session, by reservation only!

After a slideshow presentation on how baby turtles grow to adulthood, why they lay eggs in the Ogasawara Islands, and how they hatch from eggs and return to the sea, you can interact with the baby turtles that hatched the day before (hatchlings from eggs protected at Omura Beach), and finally release them with your own hands. ⇒Click here to learn about our egg protection program

You will definitely be impressed by the cute appearance of these baby turtles! While participating in our sea turtle conservation activities, you will also create precious memories unique to the Ogasawara Islands in summer!

Date and time: 18:30- (slot 1) / 19:30- (slot 2), the day before arrival at port

*Held only during the hatching season from July to October.
