About
The Jikiden Reiki Institute in Kyoto is the home of the most direct Japanese lineage of Reiki practice. Chiyoko Yamaguchi learned Reiki in 1938 from Chujiro Hayashi, himself a direct student of Mikao Usui, and practiced Jikiden Reiki (taught directly, without Western additions) for more than sixty years. The institute she founded with her son Tadao Yamaguchi now teaches the authentic Japanese-born practice from its headquarters in central Kyoto, with a global network of certified teachers (shihan) and a formal instructor registry.
Its seminar program is dense and current: three-day courses and shihankai (teacher training) run monthly through Tokyo and Kyoto, with the 2026 calendar listing sessions from November into December. The institute publishes its own textbooks and certificates, maintains the Gokai (the five precepts) recipients list, and runs the NPO Jikiden Reiki Kenkyukai international association alongside events and experience sessions.
The numbers tell the story of a living institution: as of late 2026 the registry counts 543 shihan, 1,368 shihankai (senior instructors), and 45,795 total seminar graduates worldwide. Everything is taught in the Japanese tradition the Yamaguchi family kept intact across a century of uninterrupted transmission. The institution's stated mission: To teach authentic Japanese Reiki in the direct lineage of Usui, Hayashi and Yamaguchi.

History
Jikiden Reiki descends from Chiyoko Yamaguchi, who learned Reiki in 1938 from Chujiro Hayashi, a direct student of Mikao Usui, and practiced the unbroken Japanese lineage for over sixty years. She and her son Tadao founded the institute in Kyoto, which now runs monthly seminars in Tokyo and Kyoto, teacher registries (543 shihan, 1,368 shihankai, 45,795 graduates as of October 2026), and the NPO international association.
