A new facility that combines a “jiu-jitsu” and a personal training to support overall wellbeing. We proposed a perceptual environment that aims to maximize the athlete's performance through dynamic encounters between the person and the environment. The location is in the urban area of Tokyo, and it was planned on the top two floors of skyscraper. 

The atrium is surrounded by a 10-meter-high glass curtain wall. The lower floor, which will be used as a jujutsu dojo, is zoned with curved surface against a distorted floor plan, aiming for a space composition without frontality. The gently curving wall surface is constructed from a random series of 414 aluminum pipes including seven different sizes from φ30-150. The depth of the appearance, which changes depending on the position of the viewer, is like a natural object, and it has an aspect that brings out the human instinct. In addition, the seamless detail without edges not only looks beautiful, but also has a shape that will not hurt the body even if the athlete touches the wall during the competition. 

The upper floor, which is used as a training gym, has a spatial configuration that sandwiches the training area between two wave-shaped walls. Corrugated sheets of 4200-4600 mm high and 800 mm wide were welded and buffed on site to create a giant mirror wave without joints. The mirrored corrugated plate, dyed translucent green, changes its appearance depending on the weather and time of day, and it is being as an installation to motivate athletes. In the atrium, an ultra-lightweight tensegrity fabricated from carbon fiber is suspended to develop a connection between the upper and lower floors. Sculptural forms inserted into an inorganic building covered with glass create an environment that responds to the body.
