Cancellation Policy

The shop will charge a cancellation fee in case of appointment cancellation.

Please note that the cancellation fee is 100% of the full amount and the appointment cannot be canceled on the day of the appointment itself.

★Please note: Appointments cannot be canceled or changed once made, so please think carefully before making an appointment.
The shop will pay the insurance fee and instruction fee for each participant in advance after the appointment has been made. 100% of the full amount will be charged as the cancellation fee regardless of the reason for the cancellation.

1. Cancellation policy and change of venue due to the sea condition.
2. The trip shall not be canceled due to rain, strong wind or low temperature.
3. Please confirm your own health condition in advance.

1. Please note that our shop has a cancellation policy.
Please do not cancel appointments at the last minute stating personal issues as reasons. Illnesses are considered as customers’ own health management problems; hence, we will still charge the cancellation fee.
We receive overwhelming booking requests from customers but persist on giving priority to those who have already made appointments with us by fixing their schedules, dispatching instructors and preparing diving equipment in advance for them. We hope that you can understand our difficulties in this matter.
To protect the rights and interests of other customers, please be sure to observe the cancellation policy.

Please do not use your own judgment in terms of the weather condition. We will make decisions on whether the sea condition warrants cancellation of the trip.
As it is a nature experience trip, it will not be canceled merely due to the inability to visit Blue Cave. It is not just a trip to the Blue Cave that we are offering, but a nature experience trip. We will try our best to give you an experience of the beautiful nature, no matter what the circumstances. Please be sure to understand the definitions of “Nature Experience Trip” and “Nature”.
The “Nature Experience Trip” takes place in nature. The sea is inevitably calm at times and choppy at others. We cannot control the changes in nature. Nevertheless, this is the true form of nature. Please keep an open mind in your interactions with Nature to experience her diversity. The Blue Cave is not the only interesting place that is worth your anticipation. We also hope that customers can enjoy the natural scenery offered by the sea in Okinawa. Even if you fail to visit the Blue Cave, there are sure to be other fun experiences waiting for you that can only be found here in Okinawa!

2. The trip will not be canceled on rainy days as rain has no effect on diving or influence on the sea condition.
You will get wet while diving anyway, so there is no need to worry. The rainy scenery viewed from underwater will in fact be a precious experience. You will still be able to enjoy the sight of many fishes and corals in the beautiful underwater world despite the rain.
Besides the rain, strong wind and low temperature also do not pose a problem.
It is up to us, and not the customers, to decide whether to cancel a trip due to typhoons.

3. Please confirm your health condition in advance.
It is essential to confirm your health condition prior to diving. Please visit the following website and complete a final check on your health condition.
