Reiki
Usui founded the Usui Reiki Ryōhō Gakkai (臼井靈氣療法學會 in Traditional Mandarin, meaning "Usui's Spiritual Energy Therapy Society"), a society of Japanese Reiki masters. His style is assumed to have survived to the present day (assumed as no-one knows exactly how the Gakkai practises nowadays), with Ushida being the one who, upon death, substituted the presidency of the association. This society remained secret for many years and at present, the shihan (master), Masaki Kondoh, is the president of the Gakkai. Though many of their teachings still remain secret, little by little, members of this association – such as Master Hiroshi Doi – have been sharing their knowledge with the rest of the world. In spite of this, it continues to be a hermetic society, nearly impossible to access.
