(Caution) Mikomoto Island is only for advanced divers!
Due to its geographical location, strong currents can occur around Mikomoto Island, and hammerhead sharks live in these currents.
In some cases, they may swim against the current or swim long distances in search of schools.
Also, the descent is free descent in places where there are no ropes.
Hiding your anxiety while diving is not only not fun, it can also be dangerous.
If you have any concerns, please be sure to consult us in advance so we can provide appropriate support.
Participation conditions:
① Those who have participated in an &Ocean tour or have dived with Takuma Sato
② Advanced level or above with 50 or more diving experiences (can be confirmed by logbook)
3) Have sufficient experience of diving to depths of 20m or more.
④ No gap of more than 6 months (there are exceptions depending on the number of experiences)
⑤There is no problem with equalizing your ears, and you can freely descend without worry.
At &Ocean, the condition for participation is not whether you can dive, but whether you can truly enjoy it.
If you are unsure, you can refresh your skills and check your knowledge by taking a day trip beforehand.
Be well prepared and enjoy your diving to the fullest!
