Matsuya's Official X Account Eats the Large Serving Grilled Thick Pork Loin Set Meal on Meat Day

Matsuya’s official X account (@matsuya_foods) posted at 5:05 PM on May 29, 2026 to report that it had eaten the Large Serving Grilled Thick Pork Loin Set Meal, the item eligible for today’s app-only 200 yen discount under the Meat Day campaign. In a preview post the night before, at 10:00 PM on May 28, the account had called this very item “the headliner: the hearty Set Meal of Grilled Thick Pork Loin.” On the campaign day itself, the account went on to demonstrate the product firsthand on X. The post also introduced a new hashtag, #ChallengeFromMatsuyaInsider, giving the post a reader-participation angle.

Original Post

Today is #MeatDay and #DayOfHappiness, so I had the “Large Serving Grilled Thick Pork Loin Set Meal,” which is 200 yen off in the app（╹◡╹）

Honestly, this is basically a mini big-eating challenge lol

So if you’ve eaten it too, post it with #ChallengeFromMatsuyaInsider!

I might go like a few of them 😎

The opening “（╹◡╹）” is the emoticon that has become a fixture in “I ate this” and announcement-style posts since April. The post opens by covering the double context of “Meat Day” and “Day of Happiness” along with the product name and campaign condition in a single line, then follows with “Honestly, this is basically a mini big-eating challenge lol,” self-deprecatingly emphasizing the sheer volume of the Large Serving Set Meal. The final line, “I might go like a few of them 😎,” previews an active reaction to reader posts, rounding out a five-part structure.

In the eating photo, thick-cut, grill-marked slices of pork loin are arranged in a fan shape on a white round plate, with a yellow-and-orange circular pattern composited onto the upper right of the plate and a Macky & Yakky stamp in the lower left. In the background sit a large bowl of shredded cabbage and corn salad, a small dish of grated radish and chopped green onion apparently meant for ponzu citrus soy sauce, miso soup with wakame, and a rice bowl bearing the Matsuya logo — a Set Meal spread that appears to have been photographed in-store.

The New Hashtag “#ChallengeFromMatsuyaInsider”

“#ChallengeFromMatsuyaInsider,” appearing for the first time in this post, frames the volume of the Large Serving Set Meal as “a mini big-eating challenge” and encourages readers who finish it to post using the same hashtag. The post further suggests an active reaction to reader posts with “I might go like a few of them 😎,” pairing the eating report with an advance notice of feedback on reader posts. Compared with recent “I ate this” posts — such as the “Yulinji Set Meal” on May 28 and the “Hamburg Steak in Rich Umami Stew with Mushroom Duxelles Set Meal” on May 27 — which were self-contained around the account’s own impressions and questions, this post goes a step further by actively inviting reader action.

The Three-Stage Structure of the May 29 Meat Day Promotion

Looking at the official announcement and the official X account together, the May 29 Meat Day campaign was announced and demonstrated in three stages.

Date & Time Posted	Format	Content
Monday, May 25, 3:00 PM	Official Announcement	First announced the campaign details
Thursday, May 28, 10:00 PM	Official X	Previewed the campaign the night before, with a promotional banner
Friday, May 29, 5:05 PM	Official X	On the campaign day, the person behind the account ate the Large Serving Set Meal and introduced the new hashtag (this article)

While the April 29 Meat Day consisted of a single stage — an announcement on official X at noon that same day — the May 29 rollout added stages: “advance announcement → day-before preview → eating report and reader-post call on the day itself,” with the final stage expanded beyond a simple eating report into reader participation via #ChallengeFromMatsuyaInsider. It reads as a design for two-way communication on X aimed at raising awareness of the app-only discount.
