Kawasemi is a bouldering gym at Higashi-umeda in Osaka, and the most historic gym at Umeda-area.
As it is easy to access, you can easily enjoy it.
Climbing is a simple sport where you use your body to climb walls (rocks).
It can be enjoyed regardless of gender because it is necessary to devise how to climb like solving a puzzle. As a condition for using Kawasemi, there is an age limit of 18 years or older, so you can enjoy bouldering in a calm atmosphere only for adults.
