Ekoin Temple Shukubo and Zazen Retreat

Ekoin is a working Shingon Buddhist temple on Koyasan, the mountaintop monastic complex founded by Kobo Daishi in Wakayama Prefecture, and one of the temple lodgings (shukubo) on the mountain that admits overnight guests into its daily religious routine. Rather than a conventional hotel or spa, the retreat is structured around temple life: guests stay in simple tatami-mat rooms within the temple compound, sleep on futons, and are served shojin ryori, the Buddhist vegetarian cuisine prepared without meat, fish, or pungent vegetables, for dinner and breakfast. The signature offering is participation in the temple's religious practices rather than spa treatments -- a guided zazen seated meditation session led by resident monks, open to guests regardless of prior meditation experience, and a morning goma fire ritual in which monks burn wooden sticks inscribed with prayers before a central altar, both included as part of an overnight stay. Some guests also arrange an optional sutra-copying (shakyo) session, tracing Buddhist texts by brush as a further meditative practice. Ekoin's monks, trained within the Shingon school headquartered on Koyasan, lead these sessions themselves rather than delegating to outside instructors, and the temple's reputation rests on this direct access to monastic practice alongside Koyasan's UNESCO-listed Okunoin cemetery, which borders the temple grounds and can be visited on an evening or early-morning guided walk. Facilities include a shared bath (not an onsen, but a heated communal bathing room), a temple hall for the fire ritual, and simple guest wings; there are no private spa-style treatment rooms. Reservations are required and typically made through the Koyasan Shukubo Association or directly with the temple well ahead of visiting dates, particularly in autumn foliage season and around Buddhist holidays, since room numbers are limited and meals are prepared to a fixed schedule.
