Tokorozawa City is popular as a commuter town for Tokyo due to its easy access to central Tokyo, and its population is on the rise. Large-scale residential developments are underway. In addition, as the population grows, commercial facilities such as supermarkets and department stores are also being developed. However, the city's abundant natural beauty remains strong, and you can enjoy nostalgic scenery just by stepping outside the city. A famous tourist spot in Tokorozawa City is Tokorozawa Aviation Memorial Park, located on the site of Japan's first airfield. Seibu Dome, a multipurpose dome, is also visited by many people every year. Lake Sayama, selected as one of Japan's 100 best dam lakes, is also popular.
