📅 Fri, Nov 20, 2026
About this event
At Otagawa Dam located in Mori Town, Shuchi District, Shizuoka Prefecture, monthly inspection tours are held once a month, allowing visitors to tour the dam's interior, which is normally closed to the public. You can explore the labyrinth-like dam interior spreading underground and tour internal facilities and discharge equipment rooms in the cool air. Descending the stairs on the downstream side to look up at the massive dam also offers an extraordinary attraction. Completed in 2009 as a multipurpose dam, Otagawa Dam is intended for flood control and securing tap water supplies. The tour is free to join, with operating hours from 13:00 to 14:00. The tour will be canceled if a Level 2 heavy rain advisory is issued for Mori Town. The tour is open to elementary school students and older; preschool children must be accompanied by a guardian. Participating in comfortable walking shoes and easy-to-move-in clothing is recommended.
