Current Reiki practice can be traced to the teachings of Mikao Usui in Japan during the early 20th century. Usui's teachings included meditative techniques and healing practices. One of Usui's students, Chujiro Hayashi, further developed the healing practices.
An American lady, named Hawayo Takata, learned Reiki from Hayashi in Japan and introduced it to Western cultures in the late 1930s. The type of Reiki practice taught by Hayashi and Takata may be considered traditional Reiki.
Numerous variations or schools of Reiki have since been developed and are currently practiced.
