Hyotan Jima

This is one of Japan’s three major clear streams and has a high level of clarity. The water depth is often 3-6 meters, but in some places it can be over 10 meters in depth.

Omi Maiko on Lake Biwa’s west shore in Otsu, Shiga, is the prefecture’s only dive site. Its clear waters let beginners enjoy experience and fun dives while spotting freshwater fish like ayu and black bass, offering a unique charm distinct from ocean diving.

About 10km south of Echizen, Minami Echizen is a diving area that has opened relatively recently. It is very accessible from the Kansai and Chubu areas, so many divers visit here. There are more than 20 dive sites on the beach and by boat.

You will need to be taken to the beach by a service boat from Kamiko Fishing Port, as there is no access from land. Thanks to its location inside the bay, it is not affected by major weather conditions. Entry is from a sandy area, and the water gradually gets deeper. You can also ensure the water is deep enough for a restricted water area. To the right of the entry (north), there are rocky areas where bottom fish live.

A 10-minute boat ride from Kamiko Port, this uninhabited island site features a drop-off from 5m to 40m+, attracting schools of Spanish mackerel, yellowtail, kanpachi, and horse mackerel. Best dived in summer, it offers dynamic scenery but is challenging in winter.

Kabushi Iwa in Echizen-cho, Fukui, is a beach-entry dive site ideal for beginners, with depths up to 12m. It features complex reefs, tunnels, and stable summer conditions. Divers can spot schools of horse mackerel, barracuda, nudibranchs, and enjoy the “First Tunnel” with natural air pockets.
