History and Lineup of the Mugen Kushi Series
1. Mugen Garlic Horumon Kushi (Sales ended)
The "first generation" Mugen Kushi, whose sales regrettably ended on December 31 last year. It was the catalyst for the boom, receiving strong support from many customers and recording cumulative sales of 14 million units (*).
Its main feature was the powerful special garlic soy sauce tare. Many customers became addicted to it.
Although sales ended on December 31 last year, its "addictive quality" and "fun" have evolved further, passing the baton to two new types of Mugen Kushi.
2. Mugen Dotemiso Horumon Kushi
This is a "rich and hearty" Mugen Kushi that went on sale in January 2026.
It uses a special dotemiso sauce, which is a golden ratio blend of the special dotemiso used in popular dishes like "Beef Tendon Doteni" and the special dashi used in signature dishes like "Tanaka's Kasu Udon."
The rich sweetness of the miso and the umami of the dashi intertwine with the beef horumon, creating an exceptionally satisfying bite. The balance of sweetness and saltiness is exquisite, making it a rich skewer that makes sake flow endlessly.
3. Mugen Yuzu Ponzu Horumon Kushi
This is a "refreshing and invigorating" Mugen Kushi that went on sale in January 2026.
It combines fragrant yuzu ponzu with Tanaka's special dashi, accented with spicy momiji oroshi (grated daikon with chili).
The unique texture of beef horumon and the refreshing acidity of citrus fruits are exquisitely matched.
With a light and clean aftertaste that you won't get tired of no matter how many you eat, it's a skewer that goes perfectly with both alcoholic beverages and soft drinks.

Make Mugen Kushi even more enjoyable! Even more delicious! "Mugen Kushi Exclusive Sour" is born
To make Mugen Kushi even more enjoyable for customers, two types of Mugen Kushi exclusive sours will go on sale from April 1st (Wednesday). These are playful drinks from Kushikatsu Tanaka, with carefully chosen names.
■ Mugen Kushi Exclusive Sour "Tsundere"
This is a dry sour that you won't get tired of, with the sourness of lemon and lime and a hint of saltiness.
The "tsun" (sharp) acidity and strong carbonation reset the richness of kushikatsu every time.
The aftertaste is refreshing, but a lingering flavor invites the next bite – the "dere" (sweet/affectionate) part.
This expresses the dynamic flavor that "pushes you away then draws you in."
■ Mugen Kushi Exclusive Sour "Yorisoi" (Snuggling Up)
This is a light and easy-to-drink sour with the gentle sweet and sour taste of plum and the refreshing taste of grapefruit.
It features a mild sweetness that subtly enhances the flavor of the skewers without overpowering them.
This expresses its position as a tireless partner, as if "following one step behind the main character, kushikatsu."
