Matsuya’s MEGA-Mori Fair Returns for One Week
Matsuya Foods Co., Ltd., headquartered in Musashino, Tokyo, will hold the “MEGA-Mori Fair” at Matsuya, its chain serving gyumeshi (beef bowls), curry, set meals and other rice bowls, starting at 10:00 a.m. on Tuesday, October 13, 2026. The fair features two popular bowls: the Kimukaru Don with its rich sauce, and the Pork Loin Negi-Shio Don with its refreshing sauce. Both keep their signature flavors while being upgraded to a colossal portion that puts the meat front and center, available for a limited time only.
Why It’s Back: A Big Response to the One-Day “Meat Day” Event
The MEGA-Mori Fair was first held for a single day on August 29 this year, known in Japan as “Meat Day.” It proved extremely popular, and Matsuya received many comments lamenting its end, such as “Just one day isn’t enough!” and “I didn’t make it in time for Meat Day…” In response, the fair is returning with its sales period extended to one week. For anyone who missed out last time because of scheduling, the new period spans both weekdays and a weekend, making it much easier to find a time to visit.
The Main Draw: Double Meat and Extra-Large Rice
The biggest appeal of MEGA-Mori is its astonishing volume: the meat portion is double that of the large (omori) size. To let you enjoy all that meat to the fullest, the rice is generously served in tokumori (extra-large) size. With both visual impact and satisfying heft, it is a bowl truly worthy of the name “MEGA.”
- Meat: Double the large size
- Rice: Extra-large (tokumori)
- Flavor: The same signature taste
Because the flavor stays the same and only the portion grows dramatically, regulars who already order the Kimukaru Don or Pork Loin Negi-Shio Don at Matsuya can enjoy the familiar taste to their heart’s content.
Lineup and Prices
Kimukaru Don MEGA-Mori: ¥1,200 (tax included)
A bowl in which rich sauce and kimchi make a perfect match. The boldly seasoned meat is layered with the flavor of kimchi, keeping you coming back for more of the extra-large rice. It’s ideal for those who want to enjoy punchy flavors in a generous portion.
Pork Loin Negi-Shio Don MEGA-Mori: ¥1,140 (tax included)
A refreshing green onion and salt sauce makes this bowl hard to put down. In contrast to the rich Kimukaru Don, it suits those who want a hearty portion with a lighter finish. It’s also ¥60 cheaper than the Kimukaru Don MEGA-Mori.
Rich or refreshing? Trying both during the fair to compare them is also recommended.
