Shingon Risshū (真言律宗; "Shingon-Vinaya School") is a sect of Japanese Buddhism that integrates the pratimoksha rules, the ordination precepts of Early Buddhism (also called Root Buddhism), and the samaya rules of Vajrayana, all grounded in Shingon Buddhism's esoteric doctrine. It is noted for reviving the spirit of the Risshū sect, one of the Six Schools of Nara Buddhism (南都六宗).
The sect emphasizes adherence to the vinaya—the Buddhist monastic discipline—more than traditional Shingon Buddhism, while retaining tantric practices. Its home temple is Saidaiji Temple in Nara City.
