Hidden Cove
Hirizo Beach in Minamiizu, Shizuoka, is a secluded summer-only snorkeling spot known for its crystal-clear waters and rich marine life. Accessible only by boat from Nakagi Port (July–September), it remains untouched, with no direct road access or on-site facilities—visitors must come prepared. Its pristine setting and vibrant underwater scenery make it a favorite among nature lovers. Due to its popularity, early arrival is recommended to avoid ferry wait times. It is not accessible from Irozaki coast by public transportation.
