Zetteria’s Autumn Staple: “Tsukimi Burger Fair Vol.1” Launches August 26

Zetteria, the burger chain operated by Burger One Co., Ltd. (President: Taishi Kimura; HQ: Minato-ku, Tokyo), part of the Zensho Holdings group, will hold its “Tsukimi (Moon-Viewing) Burger Fair Vol.1” starting Wednesday, August 26, 2026, offering seven limited-time items. The tsukimi lineup is a much-loved autumn tradition, and this year’s headliner is the Zeppin Tsukimi Burger — the chain’s signature Zeppin Burger reimagined in moon-viewing style, alongside a range of distinctly Japanese-tasting seasonal items.

The Star: Zeppin Tsukimi Burger, 640 Yen

The Zeppin Tsukimi Burger pairs a thick 100% beef Zeppin patty with a silky egg cooked in-store — a special build available only during this season. It is served in a fluffy, chewy bun one size larger than Zetteria’s regular burger bun. Each bite delivers the juicy savoriness of the patty, the mellow richness of the egg, and the deep flavor of the special tsukimi sauce all at once.

Rich Tsukimi Sauce Meets Refreshing Yuzu Mayo

The flavor key this year is the combination of a special tsukimi sauce built on three kinds of soy sauce with Hatcho miso and aromatic vegetables, plus fragrant yuzu mayonnaise. The soy-and-miso depth provides a distinctly Japanese richness, while the citrus lift of yuzu keeps the rich patty and egg tasting light to the last bite. Both are used across every item on the menu, giving the series a consistent washoku-inspired character.
