Overview
This page covers Komyo Reiki, the lineage taught by the Komyo Reiki Kai under Hyakuten Inamoto, a Pure Land Buddhist monk. It sets out the lineage as described by scholars and teachers, the terms used, how the teaching is organized, how it relates to other Reiki forms, and what research exists. It is a member of the Reiki family of pages.
Where does Komyo Reiki come from?
Japanese Reiki lineages and the Hayashi line
Justin Stein's entry in the World Religions and Spiritualities Project describes Usui Reiki Ryoho as a Japanese practice that developed after the Usui Reiki Ryoho Gakkai opened its first training center in the Harajuku district of Tokyo in April 1922. Mikao Usui died on 9 March 1926. His student Chujiro Hayashi, a retired Imperial Navy captain, opened a separate Hayashi Reiki Kenkyukai around 1925, and in the mid-1930s Hawayo Takata began study at Hayashi's Tokyo headquarters before bringing the practice to Hawaii.
Yamaguchi Chiyoko and the two lineages
The same entry states that Yamaguchi Chiyoko (1921-2003) received initiations from Hayashi in the 1930s. It identifies two lineages that trace through her: Jikiden Reiki, led by her son Yamaguchi Tadao, and Komyo Reiki, led by Inamoto Hyakuten, both developed in Japan in the late 1990s. The entry also records that Yamaguchi Tadao claims his mother disavowed Inamoto before her death, so the relationship between the two lineages is a point of reported dispute rather than settled history.
Inamoto Hyakuten and Komyo Reiki Kai
Stein describes Inamoto (born 1940) as a Jodo-shu Buddhist monk, Jodo-shu being a Pure Land school of Japanese Buddhism. James Deacon's Reiki Pages entry, last updated in January 2007, describes him as an independent Buddhist priest who studied with Yamaguchi, wrote his own workbook because her teaching had been oral, and adapted what he learned to his own understanding while drawing on Buddhist concepts and possibly on Gendai Reiki Ho. Deacon also reports that Inamoto taught that Usui intended Reiki as a path to enlightenment. These are secondary accounts, and neither source documents an independent history of the school.
What do the names and terms mean?
Names of the school and the system
Deacon's entry gives the association name Komyo Reiki Kai, with kai meaning an association or society, and refers to the system as Komyo Reiki. Stein uses the form Komyo Reiki for the lineage. Other teachers use the label Komyo Reikido, and the spelling Komyo is a romanization of a Japanese word. Neither source reviewed explains the meaning of the word itself, so a gloss such as bright light could not be confirmed from the sources opened here.
Japanese terms used in the teaching
Deacon's entry uses several Japanese terms for the teaching. Shoden, chuden, okuden and shinpiden name four levels. Reiju names an initiation or empowerment, shirushi names symbols, and jumon names associated mantras. Hatsurei ho names a daily practice. Deacon notes that some symbol forms and mantra pronunciations differ from those in Western Reiki, and that the four-level structure resembles the arrangement used by many independent Western teachers. Similar words across lineages do not show that the practices are equivalent.
Relation to other Reiki lineages
Stein separates Usui Reiki Ryoho Gakkai, the Tokyo society that Usui founded, from the Hayashi line and from Western Reiki, the form that spread from Hawaii after Takata. Deacon does not discuss the Gakkai and names Jikiden Reiki only as the school Yamaguchi taught. The Machipedia page Reiki covers the family as a whole, while Usui Reiki, Western Reiki, Jikiden Reiki and Gendai Reiki Ho describe other members; the evidence reviewed here does not compare Komyo Reiki with them directly.
What does Komyo Reiki involve?
Teaching structure as described by Deacon
Deacon reports that Komyo Reiki has four levels, which the school presents as parts of one teaching rather than successive advancements. Shoden covers history, basic hands-on work and self-treatment. Chuden adds treatment of others and symbols with mantras. Okuden has a more spiritual focus on applying the principles to daily life. Shinpiden is the teacher level. Class lengths in the entry range from a few hours to several weeks, and the entry is dated 2007, so current course structure may differ.
Meditative and philosophical elements
According to Deacon, Komyo Reiki places weight on philosophy and being in the present moment. He lists hatsurei ho, anapanasati (a Buddhist breathing meditation) and a daily meditation on the Reiki principles among its practices, and reports that initiations are given repeatedly across levels. Machipedia describes related approaches under Meditation. This page gives no step-by-step instructions, and it does not reproduce symbols or other material that teachers treat as restricted.
Session and membership information
NCCIH describes Reiki generally as practitioners placing their hands lightly on or just above a person to direct energy, which the agency says has no scientific support as an energy field. No source opened for this page describes a Komyo Reiki session in detail, and none states membership rules for Komyo Reiki Kai. The school's own English-language pages could not be opened during research, so membership and current teaching structure as the school states them remain unverified.
What is Komyo Reiki used for?
Spiritual development and self-treatment
Deacon reports that Inamoto taught Reiki as a path toward enlightenment, and that the Komyo curriculum includes self-treatment, daily meditation and attention to everyday life. In this account the emphasis is on spiritual practice and personal discipline rather than on treating particular medical conditions. These statements describe what the school teaches, as relayed by a third party, and do not show that any outcome occurs.
General Reiki claims in context
NCCIH states that Reiki has been studied for conditions including pain, anxiety and depression, and that practitioners describe it as supporting the body's own healing response. The agency says that this energy account lacks scientific evidence. Whether practitioners of Komyo Reiki make condition-specific claims is not documented in the sources reviewed, so none are recorded here.
What does the research show?
No independent studies of this lineage found
No trials, observational studies or reviews of Komyo Reiki were found. PubMed searches run on 2026-10-17 for Komyo Reiki and for Inamoto together with Reiki returned no records. A search on Jikiden Reiki, Japanese Reiki and Usui Reiki Ryoho returned only general Reiki results, and none of them tested this lineage. The absence of studies is not evidence of benefit or of no effect; it means the question has not been tested.
Reviews of Reiki in general, kept separate
A systematic review by Hauptmann and colleagues (2022) searched five databases for trials of bioenergy therapies in people with cancer, including Reiki. It found eight randomized trials of Reiki. Some reported short-term gains in quality of life or pain compared with rest or usual care, but none showed Reiki superior to active or placebo controls, and the authors noted small samples, limited blinding and weak side-effect reporting. NCCIH similarly states that Reiki has not been clearly shown to be effective for any health purpose.
Why general findings do not transfer
These reviews cover Reiki as delivered in the included trials, mostly in cancer-care settings, and do not identify which lineage was used. Findings cannot be carried over to Komyo Reiki, whose teaching includes meditation and a distinct initiation structure according to Deacon. The reviews also cannot be read as evidence for any condition outside the populations and outcomes they examined.
What are the safety considerations?
What sources state about harms
NCCIH states that Reiki has not been shown to have harmful effects, and the Hauptmann review reports that included Reiki studies recorded no adverse effects. The same review notes that the tools used to record side effects were not discussed, so the harm data are weak. An absence of reported harm in small trials is not a guarantee of low risk for every person or setting, and nothing opened covers Komyo Reiki specifically.
Care boundaries
NCCIH advises discussing decisions about treatment or care with a health care provider and states that its Reiki information is not a substitute for medical expertise. Reiki is therefore described here as a complementary practice and not a replacement for medical assessment or necessary treatment. This page is educational and is not individualized advice. No training standard or professional register specific to Komyo Reiki was found in the sources reviewed.
