NEXCO East Japan City Food Co., Ltd. (Headquarters: Minato-ku, Tokyo) will launch the "Nambu Tekki Charbroiled Burgers," a direct-flame grilled hamburger utilizing traditional Japanese Nambu Tekki, on May 1, 2026 (Friday) at the gourmet burger and sandwich restaurant Homework's Hiroo store, as part of its 40th-anniversary initiative.
Homework's has been serving charbroiled hamburgers using a 'rostel' (a metal grill placed directly over a flame for searing meat and ingredients) since its inception. For this new offering, they have newly adopted a Nambu Tekki-made rostel, a key element in their cooking process.
For this project, they commissioned Oigen Foundry Co., Ltd., a long-established Nambu Tekki manufacturer founded in 1852 with its headquarters in Oshu City, Iwate Prefecture, to specially develop a dedicated cast-iron rostel for grilling hamburger patties. By combining Nambu Tekki's high heat retention with the intense heat of a direct flame, they have achieved a texture that is both crispy on the surface and juicy with abundant meat juices inside.
This initiative proposes a new burger experience unique to Homework's, fusing American burger culture with Japan's proud traditional casting technology.
A New Challenge to Commemorate Our 40th Anniversary
Homework's, born in 1985 as Japan's first gourmet burger and sandwich restaurant, has been loved by many customers for 40 years.
As they reach their 40th anniversary, their theme focuses on "Uniquely Japanese Value," leading them to Nambu Tekki, a traditional craft with approximately 400 years of history. The distinct heat retention and uniform heat conduction of cast iron are globally recognized for their ability to maximize the flavor of ingredients.
By applying these Nambu Tekki characteristics to hamburger patty cooking, a new cooking method has been created to achieve an unprecedented finish.
Joint Development of Nambu Tekki Manufacturer and Custom Cast-Iron Rostel
For this project, they collaborated with Oigen Foundry Co., Ltd., a renowned Nambu Tekki manufacturer, to custom-produce a cast-iron rostel specifically for hamburgers.
When heated to high temperatures over a direct flame, the cast-iron rostel forms a fragrant crust on the patty's surface and effectively seals in the meat juices within.
This innovative approach of incorporating Japanese traditional crafts into hamburger cooking has been introduced at Homework's.
