About this site
Osezaki sits on a narrow peninsula on the western side of Suruga Bay in Shizuoka Prefecture, on the main island of Honshu. The site is known for calm, sheltered shore diving on the bay side of the point, drawing divers from the Tokyo and Nagoya areas for muck-style diving over sand and gravel slopes. Divers commonly report small marine life such as octopus, nudibranchs, and various small fish typical of temperate Japanese waters, with the bay side offering easy entries suited to a range of experience levels. Depths near shore are shallow, dropping off gradually further from the point, making it a popular training and macro location rather than a dramatic wall or drift dive.
