Katsuan Co., Ltd. (President: Takuya Teshima; headquarters: Minato-ku, Tokyo), the tonkatsu specialty chain under Zensho Holdings, will hold its “Demi-Katsu Fair” starting Thursday, September 10, 2026. The star of this limited-time autumn promotion is an aged pork loin cutlet generously topped with a demi-glace sauce that tastes like it came straight from a classic Japanese-style Western restaurant.
The Demi-Katsu Fair Kicks Off September 10
At the heart of the fair is a rich demi-glace sauce infused with the savory depth of beef, tomato and aromatic vegetables. Although full-bodied, it carries a refreshing tomato acidity that highlights the juicy flavor of the crisply fried aged pork loin. As the weather begins to cool, this deeply flavored demi-katsu makes for a perfect seasonal plate. Every set meal in the fair comes with potato salad, rice and miso soup, with the potato salad serving as an ideal palate cleanser.
Aged Loin Demi-Katsu Set: Western-Restaurant Depth
The Aged Loin Demi-Katsu Set lets you enjoy the demi-glace-topped aged pork loin cutlet in its purest form. It is priced at 980 yen for 80g and 1,080 yen for 120g. Tender aged pork loin, the crunch of coarsely ground fresh breadcrumbs and the deeply savory sauce combine for the kind of satisfaction you would expect from a neighborhood Western-style diner.
Aged Loin Demi-Cheese Katsu Set: Three Cheeses
Also joining the lineup is the Aged Loin Demi-Cheese Katsu Set, which layers a cheese sauce over the demi-katsu. Made with mozzarella, red cheddar and Egmont, the thick sauce harmonizes with the demi-glace to add even more richness. Prices are 1,080 yen for 80g and 1,180 yen for 120g.
Aged Loin Demi-Tama Katsu Set: A Tsukimi Touch
Timed for Japan’s moon-viewing (tsukimi) season, the Aged Loin Demi-Tama Katsu Set pairs the cutlet with a deep-fried soft-boiled egg shaped to resemble the moon. Crisp on the outside and runny within, the egg fry is best enjoyed dipped into the rich demi-glace sauce. Prices are 1,130 yen for 80g and 1,230 yen for 120g. The soft-boiled egg fry is also available on its own for 230 yen and is served uncut.
