Matsuya is bringing back its MEGA Mori Fair across Japan from October 13, 2026, with two rice bowls featuring twice the usual amount of meat and an extra-large serving of rice.
The fair will run at Matsuya restaurants nationwide, except for some locations, giving diners a substantial option to add to a Japanese fast-food route. Service begins at 10 a.m. on October 13 and ends at 10 a.m. on October 20.
The menu includes Kimkaru Don MEGA Mori for ¥1,200 and Pork Loin Negi-Shio Don MEGA Mori for ¥1,140. Both prices include tax, and the bowls are also available to take home.
About the Matsuya MEGA Mori Fair
The two bowls keep the familiar flavors of Matsuya’s popular dishes while making the meat the centerpiece. The Kimkaru Don combines a rich sauce with kimchi, while the Pork Loin Negi-Shio Don uses a lighter green onion and salt sauce. Each MEGA serving comes with meat at twice the standard large portion and rice prepared in the extra-large size.

Matsuya says the fair has been expanded after strong reactions to its one-day meat-focused promotion in August. The returning menu is designed for diners who want a heavier bowl without changing the core flavors of the original dishes. The double-meat format and extra-large rice make the portions notably larger than standard menu servings.
Customers can also use Matsuya’s mobile ordering and Matsuya Foods app to check available offers and coupons. Store conditions may differ, so it is best to confirm availability before visiting. For takeaway orders, remember that miso soup is charged separately.
