This is just a small local boulder gym and rather than it being the "best bouldering gym ever!" keep your expectations low-this recommendation is just a nice option for those who want to get some climbing in. There are a few nice walls in the gym and the locals are usually super friendly. If you are a regular climber, you will find out how Japan has smaller height walls and short climbs but they do increase the difficulty.

Shoe rental is available here and chalk is free! The cost to climb is around 1500 yen per person and keep an eye on the opening hours
