Kodokan, Educational martial arts institution in Kasuga, Tokyo, Japan
The Kodokan is a martial arts facility in Tokyo with eight floors above ground and a basement level, designed specifically for judo training. The building contains multiple training areas spread across different levels and features a large main dojo accommodating several simultaneous training sessions.
A founder named Kano Jigoro started in 1882 with just nine students and minimal mats at a small temple, before the facility expanded later. The concept he developed spread far beyond Japan and continues to shape martial arts training around the world today.
The name Kodokan means 'the way of teaching' and reflects a focus on learning and personal growth rather than just combat. Visitors notice how practitioners here work on themselves as much as on technique, shaping how people interact on the mats.
Visitors should know the facility has multiple levels and exploring everything takes time, so plan accordingly for your visit. There are specialized areas for different training levels, so you can watch activity in particular rooms without needing to see the entire structure.
The building has a large top floor area that can host multiple competitions at the same time and includes seating for spectators. This space shows how the facility has grown far beyond simple training to become a major venue for judo events.
