After World War II, although the business that he had in Kyoto was successful, he suffered various diseases as a result of the long period of hard military life. He gave up his business to concentrate on the treatment, but in the process, he had a fateful encounter with chlorella. As a result of his tremendous effort, his disease recovered miraculously. Then Nakayama, who fell in love with the organism call chlorella during his own treatment experience, believed that it was his mission to let as many people as possible know about the joy and surprise he felt, and he devoted his life to the research and dissemination of chlorella.

In 1969, when Nakayama was 54, he and his wife established a chlorella sales company called Heian Chlorella Jeffcy Co., Ltd. Originally they sold chlorella in their retail shop, but in order to bring chlorella to more people, to provide it reliably and securely to customers, and to make sure that only correct information was given out, they changed to a direct sales mail order system.

Burning with an inquisitive spirit, Nakayama sent chlorella out into the world with confidence that it would undoubtedly be accepted, and always continued the search for the consistently best, authentic quality. This was also shown by the fact that the proprietary method of crushing chlorella cell walls was approved as a patent in Japan and the United States.

At the same time, believing that “the desire for health knows no borders,” we undertook expansion to other countries. Nakayama’s prescient actions have now evolved on a scale to place annual sales of the group at approximately 20 billion yen, 45 sales bases nationwide, and 19 bases in 15 countries abroad (as of September 2004). Nakayama’s founding spirit and ethics have been adopted by leading companies in Kyoto as well, and are continually passed down to group companies.
