Kousuke Yoshimura was born in June 1976 in Fukuoka city. 
His father was a sushi-chef and his mother ran a Japanese-style bar. Naturally he got interested in cooking in childhood. Aside from his regular work, he had built up his experience in a gyoza restaurant for two years. He came back to his mother's bar and he devoted himself to cooking. Though those experiences, he completed his original tonkotsu ramen by himself and opened 
 
"Hakata Ikkousha" in Daimyo, Fukuoka.
The shop was named "Ikkousha" with the hope that whoever comes here can find "one" or more "happiness" at the precious "place". He also opened "Hakata Gensuke", which was the very first Tsukemen,dipping ramen,shop in April 2008- Hakata. The concept of the shop is totally different from that of "Ikkousha".
