Nishitama district

Nishitama is an administrative district in western Tokyo's mountainous region, comprising four municipalities: Hinode, Mizuho, Okutama, and Hinohara. The area is characterized by forested hills and a lower population density compared to central Tokyo.

The district emerged in 1878 when the larger Tama area was divided into separate sections. In 1893 it transferred from Kanagawa Prefecture to Tokyo Prefecture, becoming part of the capital's administration.

The communities here preserve rural traditions visible in daily life, such as traditional tofu-making and farming that have passed through generations. These practices give the region a character that stands apart from Tokyo's urban environment.

The district can be reached by car or public transport, though the mountainous terrain means some areas take time to access. It is best to allow adequate time for travel between the communities rather than attempting to visit everything in a single day.

The region is home to Lake Okutama, a large reservoir that shapes the landscape and serves important functions for local water management. The lake draws visitors seeking natural settings away from Tokyo's urban areas.
