It was at this time that he first learned about western health preservation methods. Five years later, he finally overcame all diseases and recovered. In the process of fighting against diseases, he summed up the conclusion that "overeating is the first of all diseases" through personal experience. Since then, he has devoted himself to promoting the popularization and implementation of the Katian-style western health law and opened Osaka Hachiba Hospital.
