Experience of the grand scale and rich nature
Nagashima Dam is one of the largest in the Oi River system. Enjoy the attractions such as the “Spray Bridge” where you can see the dam discharge up close. The mystery tunnel is also fun. You can tour the inside of the dam when you make a reservation in advance. Right in front of you is the Abt system train. It climbs the steepest slope in Japan. You can get a dam card!
