Matsuya's Official X Account Posts "Eat Whatever You Love" for September 14 "Big Eater's Day"

Matsuya’s official X account (@matsuya_foods) posted on the morning of September 14, declaring “Today, September 14, is ‘Big Eater’s Day,’” and encouraging fans to eat their favorite Matsuya dishes to their heart’s content in the spirit of autumn’s hearty appetite season. The post doesn’t announce any specific new product or campaign; instead, it pairs a single image with a short message that uses the commemorative day as an excuse to boost appetites.

“Live up to the name of a big eater” — the text of the post

The post reads as follows:

Today, September 14, is “Big Eater’s Day”

Autumn’s hearty appetite season has arrived🍁 Today, let’s live up to the name of a big eater and eat whatever we love at Matsuya to our heart’s content( ¯꒳¯ )

Using “autumn’s hearty appetite season” as a lead-in, the post frames the commemorative day’s name as a call to indulge one’s appetite. No wording corresponding to “Big Eater’s Day” appears in Matsuya’s official notices or menu descriptions, suggesting the line was written specifically for this post. The emoticon “( ¯꒳¯ )” attached at the end has been used repeatedly in the account’s “Today is ‘[Name] Day’”-style posts, and the only emoji used here is a single maple leaf, “🍁.”

The attached image places the large text “9 14 Big Eater’s Day” against a vivid yellow background, with Matsuya’s official mascot Yakky holding up a bowl at the center. Photos of Matsuya’s classic menu items — Beef Bowl, Hamburg Steak with Demi-glace Sauce, the Morning Meal, and more — radiate outward around it, bringing together a single image that conveys a table full of festive food befitting the commemorative day.

Another in a string of “[Name] Day” posts through September

The “Big Eater’s Day” post is one of a series of commemorative-day posts Matsuya’s official X account has kept up since the start of September. Looking back at past posts, the account featured “Rest Day” on September 8 and “Protein Day” on September 11, keeping to roughly a three-day interval through this latest post.

Even when the commemorative-day theme is the same, the direction of the appeal contrasts. “Rest Day” was about taking it easy and not overdoing things, while this “Big Eater’s Day” post pushes fans to eat as much as they like. There were also posts in August tied to “Chopsticks Day” and “Nutrition Day” that encouraged eating, and the pace of these commemorative-day posts leading into meals at Matsuya has been especially frequent in September.

Overlapping with the autumn menu and a seasonal turning point

The phrase “autumn’s hearty appetite season” in the post also overlaps with the autumn lineup Matsuya has been pushing lately. Since the “Stir-fried Pork and Eggplant with Spicy Miso Set Meal” went on sale on September 8, the account has kept up an “autumn”-themed run of posts, including a taste-report post on September 10 and coverage of a September 13 exhibition.

What’s more, September 14 also marks a turning point for Matsuya’s points campaigns. Matsuben Net’s Gogotoku point boost closes at 18:00 that day, and the Matsuya Mobile Order triple-point campaign ends at 23:59 the same day. With the new “Miso Soup with Pork & Vegetables Set” menu item set to launch at 10:00 the following morning on the 15th, this commemorative day’s call to “eat whatever you love” lands right as these campaign deadlines and the new menu launch converge.
