Meiji Park, a Tokyo Metropolitan Park, opened in October 2023 as the first Tokyo Metropolitan Park to utilize the Public-Private Partnership (Park-PFI) system based on the Urban Parks Act. The project site covers approximately 1.6 hectares of the front yard space of the National Stadium, and Tokyo Legacy Parks Co., Ltd., a consortium of six companies with Tokyo Tatemono Co., Ltd. as the representative organization, is responsible for the development, management, and operation of the new park. Our company was consulted by Tokyo Tatemono Co., Ltd. in 2021 and was in charge of overall planning direction and architectural design supervision. We worked closely with the client to create a new park that embodies the concept of "creating a park that will become a legacy of Tokyo, a city that the world can be proud of," and were involved in creating a new park life that meets diverse needs such as well-being and diversity. The park includes three plazas, such as the approximately 1,000 m² lawn area "Hope Plaza" and the "Path Plaza" which incorporates a water feature inspired by the Shibuya River, as well as a wooded area of approximately 7,500 m² called "Pride Forest." Furthermore, we created a lively atmosphere by incorporating publicly solicited park facilities (five retail buildings) to improve convenience for park users. Currently, each building houses a cafe, relaxation facilities, restaurants, and an outdoor activity shop. We also handled the business planning and construction (excluding the sauna area) of the first "TOTOPA" urban spa facility newly developed by Tokyo Tatemono Group*. Located on the 2nd and 3rd floors of Building A of the retail complex, it features a sauna, a cold plunge pool with a depth of approximately 160cm, a fitness area, and various lounges. *Developer: Tokyo Tatemono, Operator: Tokyo Tatemono Resort
