Frequently Asked Questions

  • Can I hire a private dive instructor?

    A private dive guide will be one of our charter services. Please ask for availability.

  • Can small children join the cruise?

    The minimum age for joining our dive cruise is 8 years. Children 8-9 can join our Discover Scuba Diving program (PADI Bubble Maker program), and those above 10 can even join our PADI certification courses. Our service is a full-day dive cruise and the sea condition could be uncomfortable for small children.

  • Can we go to Hateruma Island?

    Although not often, we could go to Hateruma island during summer when the sea condition is calm. Hateruma is approximately 1.5 hours southwest of Ishigaki, and there will be an extra fuel charge. We usually plan for Hateruma diving 4-5 months in advance. Please contact our staff if you have any interest.

  • Can we go to Yonaguni underwater ruins?

    Unfortunately not. Yonaguni is approximately 100km west of Ishigaki or 30min by flight. You need to stay in Yonaguni if you would like to dive there. The best season for Yonaguni would be December thru March. If you need any advice, please contact us.

  • Can we request diving points?

    Dive sites each day are decided by our boat captain based on the sea condition, our guests’ skill level as well as their requests. We try our best to bring you to different dive sites for each dive. We will do our best to maximize your experience with us, and happy to take your requests. Our utmost priority is safety, however, and we also have other guests on the boat, so we may not be able to meet your requests.

  • Do I need to have Enriched Air Diver (EAD) certification to use enriched air tank?

    At Prime Scuba Ishigaki, enriched air tanks are available free of charge, and you can use them on a trial basis. Please note that having basic knowledge about enriched air is important in diving safely with enriched air, and we recommend all divers be certified as EAD.

  • Do we need to wear wetsuit in summer?

    Although water temperature in summer can go up to 30C, and you can swim without a wetsuit, we recommend our guests wear wetsuits for protection from scratches and other injuries

  • Do you have a snorkeling program?

    We are sorry but we do not have a snorkeling program. Scuba diving points are generally too deep (5-20m) for enjoying snorkeling. If you would like to snorkel, we recommend using snorkeling tour operators.

  • Do you have half-day programs?

    We are sorry but we do not have half-day programs. Our services are full-day dive cruises, leaving Ishigaki port around 8:30 am and coming back around 15:30.

  • What is the number of guests per dive group?

    The number of guests under an instructor differs by program. For our Discover Scuba Diving program, we have a maximum of two guests per instructor. For the fun diving program, our usual group size is four guests per instructor.
