The Opening of Musashi-Koyama Forest Park in Saitama and the Dawn of the Large-Scale Natural Park Era—August 1974

The Opening of Musashi-Koyama Forest Park in Saitama and the Dawn of the Large-Scale Natural Park Era—August 1974 The opening of Musashi-Koyama Forest Park symbolizes the true beginning of the development of national parks in Japan. Records state, “The National Musashi-Koyama Forest Park has opened… with a project cost of 4.1 billion yen,” indicating that it was regarded as an extremely large-scale national project at the time. The defining feature of this park is that, unlike a typical urban park, it is a “nature-oriented park” that fully utilizes the vast forests and hilly terrain as they are. Whereas conventional urban parks centered on manicured lawns and playground equipment, the Forest Park adopted the philosophy of preserving the existing natural environment while reconfiguring it into a space accessible to the public. In other words, rather than artificially creating nature, it demonstrated a new approach to public space: “managing nature while opening it up to the public.” Furthermore, the park aimed to balance recreation with nature conservation. While visitors could enjoy hiking, cycling, and nature observation, the park also played a role in preventing uncontrolled development and maintaining the forests and ecosystems. This can be seen as an example of the concept of “using while protecting” being concretized as policy amid the rapid loss of nature during the period of high economic growth. Furthermore, the opening of Musashi-Kyuryo Forest Park had a significant impact on the subsequent development of national parks. As can be seen in the materials, plans for national parks were being advanced across the country, and a trend emerged in which the state took the lead in developing large-scale green spaces. Consequently, the role of parks expanded from being facilities confined to individual cities to becoming regional environmental infrastructure. In general assessment, Musashi-Kyuryo Forest Park is known as Japan’s first national park and is considered to have served as a model for subsequent parks such as Meiji Memorial Park and other national parks across the country. Its design, which leveraged the vast area and diverse natural environment, was groundbreaking in that it presented a vision for coexistence with nature in suburban areas. Thus, the opening of Musashi-Kyuryo Forest Park marked a shift in park philosophy—moving beyond the stage of artificially increasing green spaces within cities to one of utilizing existing nature while conserving it. It was a significant milestone that profoundly influenced both Japan’s environmental policy and recreational culture.
