"GINZA SKY WALK 2024" is an event themed around "ethical" behavior and lifestyles that are considerate of the environment, people, and society, offering a glimpse into a future pedestrian space that utilizes things and services that are kind to people, cities, and the environment. Leveraging our experience, we provided total support for the event, from planning and spatial concept design to construction, operation, and attracting collaborating companies. The event's experience included walking the entire 2km length of the Tokyo Expressway (KK Line) from Shimbashi to Kyobashi, enjoying the cityscape along the stage where performances by the Tokyo Brass Band Association and the Tokyo Fire Department Band could be enjoyed in the unique space of the expressway, as well as ethical content experiences such as local product shops, a market, and art displays. In addition, early morning running and yoga programs, as well as night programs to enjoy the Ginza night view, were also held, creating opportunities to experience a new charm of the KK Line that is different from that of the daytime. In line with the event's theme of "ethical," we aimed to create an event that is kind to people, the city, and the environment by installing fixtures made from Tokyo-related wood that can be reused after the event, conducting art workshops using recycled materials, and inviting partner companies that share our ethical values.
