Beta Climbing Gym is a gym where you can enjoy various climbing

You can enjoy various climbing such as bouldering, lead climbing, dry tooling, crack climbing, and multi-pitch climbing.


A rich menu of courses allows you to learn various climbing techniques

We offer a variety of courses, including lessons aimed at improving climbing skills, rope climbing courses such as lead climbing and multi-pitch, and various dry tooling courses.
Not only indoor, but also outdoor courses and practice sessions are available.


A classical gym with many outdoor-style holding problems

We have a wide selection of problems that are called holding problems. In the modern climbing scene, sport climbing is in the spotlight, and more and more climbers are enjoying climbing only in climbing gyms and bouldering gyms, rather than climbing outdoor rock faces.
In response to this situation, more and more gyms are creating problems that incorporate elements of sports so that gym-only climbers can enjoy themselves. …I guess it’s mainstream now.

At Beta, we have prepared many problems that focus on retention so that climbers who climb outdoors can enjoy themselves and train, and so that gym-only climbers can become stronger. It is one of the few classical gyms left today.


The name “BETA” has two origins

1) “Prototype”

In system development, a “prototype” is called “BETA”. This climbing gym also means that it will continue to evolve through prototypes.

I would like to create it together with all the climbers who enjoy BETA.

2) “Information”

In climbing, “information” is called “BETA”. We hope that you will visit this gym, interact with other climbers, gain information, and then take flight into the world of adventure.

We hope that interactions between our customers will create a chemical reaction and encourage them to enjoy various types of climbing in a variety of fields.
At Beta, we do our best to help with this.
