2-hour scuba diving experience at the Blue Cave in Onna, Japan

1. Things to prepare: swimsuit, towel, sandals, and change of clothes. ※It is recommended to wear your swimsuit in advance. If you are prone to seasickness, please bring your own motion sickness medication.

2. Due to unpredictable sea conditions, if waves are too strong and the Blue Cave is unsuitable for island landing or water entry, we will change to alternative diving areas. These backup sites are also our carefully selected dive spots with beautiful coral reefs and fish schools. If you do not accept the change, we regret to inform you that refunds cannot be issued. Thank you for your understanding.

3. If the alternative sea area conditions are also too severe for sailing, we will notify you on the same day and issue a full refund.
