This dive site, Hasama Ocean Park, is situated in the calm inner bay of Tateyama on the Boso Peninsula. While a beach is present, boat diving is the primary way to access the main attractions. The standout feature is the 'Takane' point, just a 5-minute boat ride from the harbor, where an underwater shrine complete with a striking large torii gate offers a unique and memorable diving experience. The site navigation is generally straightforward around this distinct landmark.
Underwater, the park bursts with life, characterized by extensive soft coral formations that are home to a bustling array of colorful reef fish. For macro photography enthusiasts, the site is a treasure trove, featuring interesting creatures such as lobsters, various species of nudibranchs, and well-camouflaged frogfish hiding within the vibrant coral gardens and rocky crevices.
Given its inner bay location and shallow depths, Hasama Ocean Park is enjoyable year-round, although specific seasonal highlights for visibility or marine life are not detailed. It is highly suitable for both scuba divers of all skill levels and freedivers, offering accessible depths and captivating subjects, from the unique underwater shrine to its rich biodiversity.
