Diving Area

Diving area is loosely divided into three: around Chichijima Island, Hahajima Island and Kater Island.

The diving points around Chichijima Island (including Anijima Island) are within thirty or forty minutes at furthest by boat. There are more than fifty various points such as splendid points including dropoff and large migratory fish and calm points of beautiful sands and abundant corals, here and there in this area. Also, there is a number of shipwrecks sunk during the war, and this is only area for genuine wreck diving in Japan.

Kater Island is located about fifty kilometers north of Chichijima Island, and it takes more than two hours by boat. Therefore, it cannot be reached in any season other than summer with the wind dying down. It is one of the world’s most superb diving areas and the Ogasawara’s biggest diving points such as Tuna Cave of Yomejima where more than 100 dogtooth tunas gather and Shark Cave of Kitanoshima where sand tiger sharks gather are scattered about the area. In summer season, many divers come towards Kater Island.

Diving around Hahajima Island has been open since 1999 and it is still unknown sea area. But therefore, you can enjoy diving, fully feeling adventurous. (unfortunately, there is no point map)

If you wish to make a dive around Kater Island and Hahajima Island, please make sure to take a diving course around Chichijima Island beforehand and check you have enough weight adjustment and buoyancy skill, etc.

Diving Style

All dives are made from a boat, and the dives are usually drift style without anchoring. You may be involved in quite strong current according to the spot. However, it is enough for even beginners to enjoy the Ogasawara’s sea by dividing into groups by skill level, or changing an entry point. Also, there are plenty of points for anchoring in a calm place, and slowly enjoying watching fishes.

A daily schedule is that you go to the sea at around 8:30 a.m., make the first dive in the morning and the second dive in the afternoon. If you wish to make one more dive, it is possible to add the third diving as an option by sparing lunch time for the third diving. So, you can make up to three boat dives a day. You will return at around 3:00 p.m., though the return time depends on the diving point.

Basically, once leaving the port in the morning, you will not come back till the return time, and you will have lunch on the ship.
