Frequently Asked Questions (FAQ) about diving in Tokashiki Island

Q. Is it okay if I am a complete beginner or can't swim?
Yes, you can! Our instructors provide one-on-one support for the "Experience Diving" program. Using buoyant equipment, even non-swimmers can enjoy the Keramas blue world as long as they master breathing techniques.
Q. Can I always see sea turtles?
Although we cannot guarantee a 100% encounter with wild animals, Tokashiki Island has a very high encounter rate among the Kerama Islands. If you choose a tour that targets frequently occurring points such as the "Aligarh Cable," you have a high probability of encountering these animals!
Q. Is it possible to go diving from Naha on a day trip?
It is possible! The island is only about 35 minutes from Naha (Tomari Port) by high-speed boat. It is common to take the morning flight to the island, enjoy two dives, and return on the evening flight.
Q. Is diving held on rainy days?
Even if it rains, it does not matter once you are in the water, so as long as there are no problems with ocean conditions (high waves and strong winds), the event will be held. The transparency of Keramas blue is often maintained even on rainy days, so don't worry☆.
Q. Can I board a plane immediately after diving?
No, you can never board. To avoid the risk of decompression sickness due to changes in air pressure, you must allow at least 18 hours (recommended 24 hours) between diving and boarding the plane. On the last day of your trip, change to snorkeling.
