About 'Kitchen Origin' and 'Origin Bento'

'Origin Bento' was established in 1994 as a new-style bento shop offering a wide selection of prepared foods sold by weight, allowing customers to freely choose their favorites. With a strong commitment to in-store cooking, every dish is freshly prepared daily with care.

'Kitchen Origin' opened in February 2014 in Ikebukuro, Tokyo. While offering the same product lineup as Origin Bento, it features a refreshed, calm store design that appeals to female customers. Some locations include an eat-in corner, allowing quick meals and flexible use according to lifestyle needs. Kitchen Origin and Origin Bento offer over 40 types of bento boxes, including made-to-order bento cooked just before serving and ready-made bento displayed fresh in-store. Prepared dishes and salads are portioned into convenient packs for easy selection. With a wide variety of bento, rice balls, and vegetable-rich side dishes and salads, the lineup makes everyday dining enjoyable. Whether for a regular meal or to add just one extra dish, please visit Kitchen Origin or Origin Bento.
