After graduating from Niigata Cooking Technical School, Mr. Shimbo worked at various restaurants in the city and studied the basics of Italian cuisine.
 From 2009, he worked as head chef of a restaurant with strong local ties in Shonan in Kanagawa prefecture, and in 2011 he worked in collaboration with local farmers as head chef for a shop in Shonan-Chigasaki, which specialized in natural Italian cuisine and wine.
 After that, he traveled across Japan to see what people, food, and places he could encounter.
 During his travels, he came to the realization that his hometown of Niigata had great potential unknown to people outside the prefecture. He then moved to Niigata city with his family with the goal of unleashing that potential and sharing it with people all over the country.
 From 2017, in addition to working as the owner of Armonia, he has been active with various activities including lecturing, cooking on the Niigata restaurant bus, product development projects in collaboration with food product makers, and more.
