  • Sightseeing
Completed in 2013, the Isawa Dam is one of the largest central-core rockfill dams in Japan, with an embankment height of 127 meters, a crest length of 723 meters, a volume of 13.5 million cubic meters, and a total water storage capacity of 143 million cubic meters. Many visitors come to view the mountains in autumn when the leaves turn red, and in winter when they are covered with snow. Near the Isawa Dam is the "Oshu-ko Koryukan" (Lake Oshu Exchange Center), where the local area, history, and water-related topics are displayed in an easy-to-understand manner using panels, models, and photographs. Visitors can also experience activities such as rafting and canoeing, so if you are interested, please check it out!
