Buddhist meditation gathering (or Zazen Gathering) is one of the many activities regularly hosted by Buddhist Zen Temples. As an overlapped activity between a traditional religion and contemporary society, the Buddhist meditation gathering can be considered as an irregular non-belief religious experience for average citizens. This article studies Buddhist meditation gatherings as a part of ritual process from the ordinary to the extraordinary and back to the ordinary. Participants of these Buddhist meditation gatherings, both Japanese and non-Japanese, are first separated from their daily life, and then participate in a new meditating gathering to have non-daily experience and a sort of communitas in transition, and return to daily life by incorporating meditation practice into their daily lives.From February to November, 2015, the author participated in several Buddhist meditation gatherings at Soji-ji Temple, the Daihonzan (head monastery) of the Soto Zen School, and delivered questionnaires to participants for answers regarding their social status, their motivations, and their experiences of meditation and how these activities influence their lives. This article analyzes and discusses their responses and examines the meaning of Buddhist meditation to common people in modern Japanese society. It also draws an attention to differences found in the responses between Japanese participants and non-Japanese participants in these Buddhist meditation gatherings, in which non-Japanese participants emphasize their experiences of “Japanese culture” at the Buddhist meditation gatherings.
