Noboribetsu Date Jidaimura (Edo Theme Park)

An Edo-period theme park with a recreated town where you can watch a ninja show at the Ninja Kasumi Mansion and an oiran performance in the traditional culture theater. It's a short bus ride from Noboribetsu Onsen, so it pairs easily with a hot-spring stay; check the show schedule on the official site before you go.
