An hour west of Shinjuku, Mount Takao (高尾山; 600m), also referred to as Takao-san, is a particularly pleasant place for a quick escape from Tokyo, and a starting point for longer trails into the mountains in the Chichibu-Tama National Park (秩父多摩国立公園). The Keiō line from Shinjuku provides the simplest and cheapest way of reaching the terminus of Takao-san-guchi (1hr). After a hike up or a ride on the cable car or chairlifts, you’ll get to Yakuo-in (薬王院), a temple founded in the eighth century and notable for the ornate polychromatic carvings which decorate its main hall. It hosts the spectacular Hiwatarisai fire ritual on the second Sunday in March back in Takao-san-guchi, where you can watch priests and pilgrims march across hot coals – and even follow them yourself.
