Discover the Isawa Dam (Lake Oshu), one of Japan's largest rock-fill dams, completed in 2013. Located in Oshu City, Iwate Prefecture, a 40-minute drive from Mizusawa IC on the Tohoku Expressway, the dam features a 127-meter high embankment and a 723-meter long crest. Lake Oshu offers stunning seasonal views, especially during the autumn foliage. Visitors can walk along the dam's top (when open), explore the visitor center with exhibits about the dam's construction and local nature, and obtain a commemorative dam card. The best time to visit is during the day to fully appreciate the panoramic views.
