Matsuya's Official X Promotes All-Size 70-Yen-Off Beef Bowl X Coupon With a 'Find the 390' Quiz

On the morning of August 14, Matsuya’s official X account (@matsuya_foods) promoted a coupon that brings the Regular Serving Beef Bowl down to 390 yen, framing it as a number quiz challenging readers to find the hidden “390” in an image. The post, boldly captioned “Find the 390 Yen!,” calls on readers to “reply with the answer!” — a playful, game-like way of re-publicizing the “first in two years” X Coupon currently underway.

A Number Quiz to Find the “390”

The image is filled with a grid of only the digits “3,” “0,” and “9,” and readers are challenged to spot the “390” hidden within it. In one corner of the grid sits a magnifying glass zooming in on the numbers, while beside it Macky ponders with a question mark floating overhead. The post’s caption asks, “Everyone, how many seconds did it take you to find the ‘390’?” — a time-attack-style challenge that turns the search into a race against the clock.

The “390” hidden in this sea of numbers is the exact price of the Regular Serving Beef Bowl after the coupon is applied. The Regular Serving Beef Bowl normally costs 460 yen, and using the coupon brings it down 70 yen to 390 yen.

70 Yen Off Beef Bowl in All Sizes, Valid Until 10:00 a.m. on August 18

The bottom of the image spells it out clearly: “Actually, it’s 70 yen off Beef Bowl in all sizes!” — meaning the discount applies uniformly across every size of Beef Bowl, not just the Regular Serving. The expiration is listed as “2026.8.18 (Tue) 10:00,” so the coupon can be used through 10:00 a.m. on Tuesday, August 18. It is valid at “all Matsuya stores except some locations.”

How to Use It: Scan the QR Code at the Ticket Vending Machine

For instructions on using the coupon, the image includes a QR code along with the guidance: “First, hold this QR code up to the QR code reader on the ticket vending machine.” The process starts with scanning the code at the vending machine before placing an order, and readers are directed to the post for further details.

Re-publicizing the “First in Two Years” X Coupon Currently Underway

This coupon is part of the “X Coupon” that launched on August 11, which Matsuya had previewed in advance as its “first in two years.” Since the campaign began, the official X account has promoted the 390-yen Beef Bowl day after day, and this time it re-publicized the offer through the angle of a number-search quiz.

Around the same time, a “Free Service Voucher Giveaway Campaign” (running through 10:00 a.m. on August 25, 2026) commemorating Matsuya Foods’ 60th founding anniversary is also underway, and the official X account frequently announces the two promotions together. The 390-yen Beef Bowl X Coupon expires earlier, at 10:00 a.m. on August 18, ahead of the voucher giveaway.
