UR Toshi Kiko Hagiyama danchi UR都市機構萩山団地, in Kodaira-shi (map). This danchi is immediately south of Hagiyama Station 萩山駅, at the meeting of the Seibu Hajima line and the Seibu Tamako line. Just north of Hagiyama Station is Sayama Green Road 狭山・境緑道 / 多摩湖自転車道, a cycling/walking path that follows a former canal. (See: The Kodaira Referendum: fighting for Democracy in the Acorn Forest).
Additionally, Tama Cemetery is nearby to the east, as is Kodaira station, just one stop away.
