Diving in COVID-19 pandemic

(Caution) Mikomoto Island is only for advanced divers!

Due to the geographical environment, strong currents may occur around Mikomoto Island, and Hammerhead Sharks are in those currents.

In some cases, they may swim towards the stream or swim long distances in search of groups.

In addition, descent is a free descent in a place where there is no rope.


Even if you hide your anxiety and dive, not only will you not be able to enjoy it, but it is also dangerous.

If you are uneasy, we will follow you appropriately, so please be sure to consult in advance.


Participation conditions:

① 50 or more diving experiences (exception if 30 or more)

(2) Sufficient diving experience with a water depth of 20 m or more.

④ ear there is no problem in the opener, that the free descent can be without anxiety


& Ocean's participation condition is not "can you dive" but "can you really enjoy it?"

If you are uneasy, you can refresh your skills and check your knowledge on a day tour in advance.

Let's prepare well and enjoy diving from the bottom of our hearts!
