The Usui teachings included teaching people how to heal themselves (a very central point still in Reiki of today). Healing would be given to them, then they were taught how to heal themselves. In 1923 on the 1st of September an earthquake shook Tokyo and Yokohama, measuring 7.9 on the Richter scale. The epicentre was 50 miles from Tokyo. Over 140,000 deaths were reported. The majority were killed in the fires started by the earthquake. It was the greatest natural disaster in Japanese history. Mikao Usui and his students started to give healing in the area and the demand and need for Reiki was enormous and as a result of his work he became even more famous. In 1925 Usui had become so busy that he had to open a new larger school outside Tokyo in Nakano. As he travelled widely his senior students would continue with his work when he was away from his school/clinic. Dr Mikao Usui passed away on March 9th 1926 at the age of 62. He is buried in Saihoji Temple in Suginami-Ku, Tokyo. Later his students created and erected a large memorial stone next to his grave describing his life and work. Much of the new information about Usui Sensei comes from the translation of this memorial.
