What the Historical Record Confirms, and What It Does Not

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Reiki's founding is unusually well documented for a healing tradition of its kind, because it began recently enough that Japanese primary sources survive, and historians, most thoroughly Justin Stein in his archival study of the practice's circulation, have been able to check the version most Western students learn against them. Some of what circulates does not hold up: the widely repeated claim that Usui was a Christian minister or university president who searched Buddhist, Christian and medical texts for the method Jesus used to heal has no basis in the Japanese record and appears to be a later invention, most likely shaped by students building a founding story that would travel well to a Western, largely Christian audience. The Mount Kurama fasting retreat itself rests on later testimony rather than a document Usui wrote himself, though it is the account his own students preserved and is not contradicted by anything else on record.

What is solidly attested is the practical chain of transmission. Usui founded a Tokyo teaching society in 1922, trained several hundred to several thousand students by his death in 1926, and Chujiro Hayashi, one of his most senior students, ran the Tokyo clinic where Hawayo Takata trained before carrying the practice to Hawaii and the American mainland. Every branch of Reiki taught in the West today traces its lineage claim through that same documented chain, whatever embellishment individual tellings of Usui's own life have picked up along the way.
