Tonkatsu Sauce Katsudon Kiraku

Komagane’s famous local dish, sauce katsudon, originated at the foot of the Central Alps and has been beloved by locals since the early Showa era (1920s–30s). Unlike typical katsudon dishes topped with egg, Komagane-style sauce katsudon features crisp pork cutlets placed atop freshly shredded cabbage and rice, all generously coated in each restaurant’s unique, secret sauce. The simple yet addictive combination of hot crispy pork, crunchy cabbage, and sweet-savory sauce has long kept diners coming back for more.

Established in 1928 during the early days of sauce katsudon’s popularity, Tonkatsu Sauce Katsudon Kiraku has proudly served its own version of this beloved dish for nearly a century. Now operated by the third-generation owner, the restaurant carefully preserves the original recipe created by its founder. Each bowl is prepared using high-quality pork, locally grown Koshihikari rice, and their special house sauce passed down through generations. This authentic, delicious meal attracts visitors from across Japan, including tourists exploring the scenic Komagane Highlands and motorcyclists touring through Nagano Prefecture.
