Diving in Japan

With 365 sites nationwide, diving in Japan covers ocean, reef, beach and wall settings. Onna and Okinawa each have 8 sites, while Shizuoka and Oshima each have 4. Diving also extends to Hokkaido and Osaka, giving the country a geographic spread that reaches well beyond its larger site concentrations.

Japan's dive sites include sandy-bottom terrain and drift diving alongside the more common ocean locations. Minami Echizen has the highest logged-dive total among the country’s leading sites, followed by Osezaki in Shizuoka. Shishihama and Kamo Aquarium East Beach are also frequently dived, while Koganezaki Park Beach gives Shizuoka another prominent location. The mix supports comparisons based on terrain and access style rather than one dominant format.
