Leaving a major consulting company, he became a washer-up at a restaurant and worked his way up to a manager. “Ho-Me-I-ku” has been developed by combining his successful employee education there, brain science, and phycology.

He has introduced this method to more than 500 companies and educational institutions, including early childhood education institutions. He also supports entrepreneurs. This method has also been used not only in Japan, but also in the U.S., China, India, Singapore, Thailand, and other countries.
