In conjunction with this year’s Gokaicho at Zenkoji, and to commemorate the opening of new Chikuma Station on the local Shinano Railway line, the Kigure New Circus will be held in a tent near Chikuma Station from 20-March to 24-May. Prices are 2700 yen for adults, 1500 yen for children, with discount tickets available in advance until 10-April. Two to three shows daily (Thursdays off).
I’m not sure what a circus has to do with Zenkoji’s esteemed once-every-seven-years Gokaicho, but it sounds like it will be fun for kids.
