Matsuya's Official X Reveals Its Kimchi Is Made In-House at the Fuji Factory

Matsuya’s official X account (@matsuya_foods) posted at 6:35 p.m. on August 9, 2026 that its kimchi is “made in-house at the Fuji Factory.” The post suggests enjoying the kimchi as-is as a snack with a drink, or adding it to the currently available Hiyajiru for a flavor twist. Rather than announcing a new product, it is a trivia-flavored post that spotlights where the kimchi itself comes from.

A Name That Matches: “Fuji Mountain Kimchi”

Matsuya’s side menu already features a dish named, fittingly, “Fuji Mountain Kimchi” (100 yen). The “made in-house at the Fuji Factory” origin described in the post lines up neatly with that product name. Fuji Mountain Kimchi is also one of the two side dishes available to choose from with the Twice-cooked Pork Set Meal (880 yen), released nationwide on July 14, and has appeared repeatedly as a spicy side dish.

The photo attached to the post shows napa cabbage kimchi heaped on a small white plate. The fresh green of the leaves, the white of the stalks, and the red marinade coating everything stand out in sharp contrast, and the kimchi looks thoroughly juicy.

Part of a Series of Ingredient Posts Built Around Hiyajiru

This kimchi post is not a one-off; it fits into a run of ingredient-focused posts built around Hiyajiru. On August 8, a post covered tofu, noting that “Matsuya’s tofu uses Hokkaido-grown soybeans,” and at 12:40 p.m. on August 9, another post said “Matsuya’s Hiyajiru goes great with rice.” The kimchi post that evening is the third in the series.

The Hiyajiru at the center of the series is the one in the Hiyajiru Set, announced in an official notice dated July 30 and released at 10:00 a.m. on August 4. Hiyajiru Only (390 yen) and the Hiyajiru Vegetable Set (730 yen) are still on sale, and the post proposes adding kimchi to this Hiyajiru as a flavor twist.

Kimchi and Hiyajiru Is Already an Official Set

The “kimchi × Hiyajiru” pairing the post suggests is actually one Matsuya has already prepared as an official option. The July 30 notice announcing the Hiyajiru Set introduced the “Bowl of Mixed Simmered Beef and Kimchi Hiyajiru Set” (30 yen off the regular price) as one of the classic Beef Bowl sets. Whether as a snack or as a flavor-twist partner, Matsuya’s kimchi and Hiyajiru have in effect already been officially paired.

Seven Menu Items Currently Use Kimchi

The following 7 kimchi-based menu items are currently on sale on Matsuya’s official website. From Beef Bowls to Lunch Sets, collaboration items, and a limited-time set meal, kimchi is offered across a wide range.

Menu Item	Price
Bowl of Mixed Simmered Beef and Kimchi	560 yen
Fuji Mountain Kimchi (side dish)	100 yen
Kimchi and Raw Egg	170 yen
Kimchi and Soft-boiled Egg	170 yen
Bowl of Mixed Simmered Beef and Kimchi Lunch Set	630 yen
ONE PIECE Bowl of Mixed Simmered Beef and Kimchi Set	760 yen
Twice-cooked Pork Set Meal (kimchi side)	880 yen

In the past, the “Mayo Kimchi Beef Bowl” (610 yen) was discontinued on April 7, and the Bowl of Mixed Simmered Beef and Kimchi Lunch Set was switched on April 7 from its old price of 680 yen to the current 630 yen, effectively a 50-yen price cut. The limited-time Twice-cooked Pork Set Meal carries a note dated August 5 reading “※To be discontinued successively,” suggesting the window to enjoy it together with the kimchi side dish is entering its final stretch.
