スポーツ ベット ボーナス was renovated and opened in October 2009. The architect Kengo Kuma created the design. Upon entering the premises, you are met with a wall of the building covered in bamboo. Roughly 680 white bamboo plants grown in Japan were used for this. This bamboo was discovered by a supervisor at Tokyo Mokkoujou Arts & Crafts Furnishings who went out and searched for bamboo on foot. He confirmed the quality with his own eyes and then used the bamboo. The ceiling of the exhibition room on the first floor is made of plywood with a bamboo veneer sheets. Using a high-quality veneer sheets of uniform length to ensure straight lines at the ends and the joints created the exquisitely finished ceiling desired by both the client and the designer.
