Far more remote and wild than any of the other diving locations in our repertoire are the Ogasawara Islands, which are technically part of Tokyo but actually lie over a thousand kilometres from the capital. For intrepid divers only, this is one of the best places in Japan to dive with dolphins and whales, and boasts some fascinating WWII wreck dives.
The highlights are the World War Two ship wrecks which provide plenty of exciting diving at different levels. From a wreck just a few metres deep and visible from Sakaiura beach to wrecks sitting at 27-45m covered in coral, marine life and even unexploded bombs and ammunition add that something extra to the dive.
Long-snouted Spinner and Bottlenose Dolphin are common in these waters all year round and often join divers.
The humpbacks come to the island waters from January through to mid-April with the sperm whales visiting from July through October. There is the chance of seeing these huge creatures up close when diving for a breath taking experience.
The waters around Chichijima and Mukojima are popular spots for seeing schooling migratory fish such as dog-tooth tuna from June until November. Other common sights around the islands are sand tiger sharks and green turtles.
