Origin of corporate name," YA" "MA" "WA"

Greater prosperity, More united.

Mr. Jokichi Watanabe, the founder of the company, decided to use shop name " YA" "MA" "WA", which he had been using in his family business instead of using his personal name. And he gave to his company the name " YA" "MA" "WA" by employing lucky words and the same connotation "YAMAWA" from ancient Japanese characters, MANYOGANA.

The meaning of YAMWA is "Greater prosperity, More united." In this words, he put a wish, as the company becomes prosperous the harmony among employees become more precious.
