1. In Japan, this term, pronounced Tōmitsu, refers to the esoteric Buddhism of the Shingon School 真言宗.
2. In China, in the early 20th century, this term came to refer to all Japanese Esoteric Buddhism, in contradistinction to "Western", or Tibetan, Esoteric Buddhism 西密. Although the term meant Japanese Esoteric Buddhism generally, in practice, most of those who promoted Japanese Buddhism in China during this time had studied in only the Shingon School.
