We are currently suspending direct bookings.
If you wish to go shark diving in Ito, please contact each diving shop listed on the ‘RESERVATIONS’ page directly.
Sorry for the inconvenience.

Check list before booking. Please let us know if you answer “no” to any of the questions below.

・Advanced Open Water certification is required.
・Diver must have a minimum of 30 logged dives.
・One year must have not passed since your last dive.
・Diver must have boat diving experience.
・Are you able to recover your regulator and also remove & replace your mask without any issues underwater?
・Depending on the day, you may encounter very strong currents when descending and ascending to and from the diving point. Are you both mentally and physically prepared for this kind of diving?
(You will not get swept away by any currents as long as you don’t let go of the drift line when entering and the descent line when descending, but please note that you will experience yourself going against the current.)
・Hound sharks may swim between you and your regulator and cause you to let go of your regulator from your mouth. We require you to calmly recover your regulator by yourself.
・Red stingrays may pull on your mask straps and your mask may come off during diving. We require you to calmly recover and replace your mask by yourself.
・Required to speak Japanese or English.
・Since we do not carry DIN type scuba tanks, please either bring a regulator that is yoke type or bring your own DIN adaptor.
We do not rent out DIN adaptors and only rent out yoke type regulators.
