Ojiya City Hall Pokemon manhole

One of four Pokemon manholes in Ojiya

The Magikarp (Koiking) manhole at the Ojiya City Hall is one of the four Pokemon-themed manholes you can find in the area, and it certainly helps to liven up what is otherwise a fairly uninteresting building, save for the koi pond on the grounds. Parking is plentiful right out the front, but if you're visiting the area via public transport it's a bit inconvenient to get here on foot from Ojiya Station (about 30min away).
