Noguchi was born in Ueno, a district of Tokyo, in September 1911. When he was three or four years old, to his surprise, he soothed another child’s toothache simply by putting his hands on it. His hands went towards the spot, without him realizing what he was doing.
This was the beginning. When he was twelve, he accomplished his first deed, curing a neighbour who had been suffering from dysentery since the great earthquake struck the Tokyo area in 1923.
From this age, he begins to receive people asking to be treated by him. At that time, he had no knowledge, not even elementary, of anatomy or medicine. Like almost all healers, he believed at first that he had exceptional powers that he alone possessed. In his teenage years, he begins to understand the consequences of his actions. He finds his own vocation but does not stop at that; he continues. He studies, through self-studies, all Eastern and Western therapeutic methods. At the age of fifteen, he opens a dojo in Iriya. At seventeen, he formulates the Precepts of Full Life (Zensei Kun), which helps to better understand his thinking. In 1930, he writes the Reflections on Integral Life, a surprising text for a young man, then only nineteen years old.
Later, in the fifties, Master Noguchi completely changes his orientation. Through his practical experience and his personal studies, he comes to the conclusion that no method of healing can save the human being. He abandons therapy and conceives the idea of Seitai and Katsugen undo. Health is a natural thing that does not require any artificial intervention. Therapy reinforces dependency relationships. Diseases are not something to heal, but opportunities for activating the body and rebalancing it. He decides to stop healing people and to spread Katsugen undo and yuki, which is not the prerogative of a minority, but a human and instinctive act.
In 1956, he created the Seitai Association, still today recognized and supported by the Ministry of National Education (but not the Ministry of Health) of Japan. Members of the association would take teaching directly from Noguchi, who also gave lectures all over Japan and wrote plenty of books. Noguchi passed away in 1976, at the age of sixty-four, at his home in Tokyo, surrounded by his wife Akiko (1916-2004) and their four children.
