Antai-ji, Zen Buddhist temple in Shin'onsen, Japan

Antai-ji is a Zen temple on a forested mountain slope near the Sea of Japan with simple wooden buildings for meditation and lodging. The grounds include rice paddies, vegetable gardens, and paths winding through the surrounding forest.

Founded in 1921 by Oka Sōtan in Kyoto's Gentaku district as a Sōtō school study monastery for the Shōbōgenzō. Kōdō Sawaki became the fifth abbot in 1949 and made it a zazen and takuhatsu practice center; his student Kōshō Uchiyama succeeded him in 1965. Under the seventh abbot Kōhō Watanabe the temple moved in 1976 to its present 50-hectare mountain site in northern Hyōgo.

The name combines characters meaning peace, stillness, and temple, reflected in the monks' quiet daily routine. Visitors experience a clear rhythm of sitting in the meditation hall, physical work in the fields, and shared meals without conversation.

Access follows a narrow mountain road that remains passable in summer. Heavy snowfall often closes the road in winter for several months, so visiting between May and October works best.

The monks bake their own bread in a handmade wood-fired oven and make miso from soybeans grown on the temple fields. Life here follows the rhythm of the seasons without electric heating in the meditation halls.
