Tokara Islands

Located between Yakushima and Amami Oshima in Kagoshima Prefecture, Japan, these small islands offer a unique diving experience. Accessible only by two village-run ferries per week from Kagoshima, the islands are a little over 160 kilometers away. The journey takes approximately 5 minutes by boat to reach the closest point and an additional 20 minutes to explore further.

Divers visiting these islands can expect to encounter mesmerizing schools of migratory fish such as bigeye trevally, bluefin trevally, Napoleon, marlin, hammerhead sharks, and stingrays. For those seeking an unforgettable encounter, there is also a manta ray point at the northern limit and an undersea hot spring point to explore.

The expedition point can be reached in 30 to 45 minutes, depending on the sea conditions. Due to the direct impact of the powerful Kuroshio Current, all dive sites are subject to a current, providing a high likelihood of encountering impressive marine life. The water temperature ranges from a warm 23 degrees Celsius in winter to a tropical 30 degrees Celsius in summer. With no rivers on the island, visibility remains excellent throughout the year, averaging between 20 to 30 meters.

For advanced and expert divers, these islands in Toshima, Kagoshima County, Kagoshima Prefecture, Japan, offer an exceptional diving experience. Make the most of your underwater adventure in this pristine location.
