🗺️ Dojima Cave Tour Boat堂ヶ島洞くつめぐり（遊覧船コース）

Located in Shizuoka Prefecture, Doujima is renowned as "Izu Matsushima," a famous scenic spot representing West Izu. The most striking feature is the cave "Tenshudou," designated as a national natural monument. Visitors can board a sightseeing boat to enter this mysterious cave and admire its stunning, dreamlike scenery. Boats depart every 15 to 20 minutes. The sightseeing boats navigate through the complex terrain of the subsiding coastline and the small islands scattered across the ocean, quickly arriving at the entrance of Tenshudou. Once the boat enters the cave, a large opening, several meters wide, can be seen at the top, resembling a giant skylight. The light streaming in from the skylight reflects on the surface of the water, creating a mesmerizing interplay of light and shadow within the cave, along with a fantastical scene of swaying and floating shapes. The deep blue water is both mysterious and beautiful, reminiscent of Italy's famous Blue Grotto. The boat will pause in the cave for a while, allowing passengers to capture stunning photos. The boat ride lasts about 20 minutes, offering a chance to enjoy the mysterious scenery created by sunlight and the cave. The cave's landscape changes with the seasons, time, and weather. It is said that each boat trip brings new discoveries and emotions. In case of storms or heavy rain, the sightseeing boats will suspend operations, so please check the official website or call in advance.

The mysterious skylight cave is a must-see attraction. The tour boats run every 15 to 20 minutes, and no prior reservation is needed. Please check the official website or call in advance for business information.
