If you’re after day-trip inspiration, we’ve got some ideas. Situated 20 miles away, Minakami is worth the drive. Explore the area starting with Ski Resort Minakami Norn, Mable Village Rock Heart Castle and Hoshi Onsen Chōjukan. The locals will also probably point you toward Tomioka, 20 miles away. If you can only see one thing here, make sure it’s Tomioka Silk Mill. (But we’re also big fans of Gunma Safari Park and Gunma Museum of Natural History.)
