Matsuya’s official X account (@matsuya_foods) posted at 6 p.m. on May 29, 2026, previewing a new menu item, “Overflowing Three-Kind Rich Cheese-Filled Hamburg Steak,” set to go on sale from 10 a.m. on Tuesday, June 2, 2026. The post highlights this special menu item, which packs three kinds of cheese into a hamburg steak, and calls out that customers can choose between two sauce lines, “Demi-glace” and “Umatoma.”

Original Post

“Overflowing Three-Kind Rich Cheese-Filled Hamburg Steak” goes on sale from 10 a.m. on Tuesday, June 2🎉

A special menu item packed with three kinds of cheese has arrived!

Choose your sauce from two options: “Demi-glace” or “Umatoma”!

Don’t miss this chance to try it!

The post opens with the release date and product name packed into a single line, signals excitement with a 🎉 emoji, then lays out the selling points in the next two lines in order: “packed with three kinds of cheese” and “choice of two sauce lines.” The final line closes with the standard “don’t miss this chance to try it.” The “(╹◡╹)” emoticon and the questions and reader-participation elements that had become standard in recent taste-test-style posts are absent this time, leaving a structure focused purely on a simple new-product announcement.

Promotional Banner Foregrounds “Overflowing Emotion.” and the Demi-glace Version

The promotional banner attached to the post places the catchphrase “Overflowing Emotion.” in bold black text on a yellow background across the top half, with white circular graphics representing the three kinds of cheese overlaid on the text. At the center sits a hamburg steak on a teppan grill, captured at the moment yellow cheese flows out of a vertical cross-section. The hamburg steak is coated in glossy demi-glace sauce, and combined with the black-banner copy on the left, “We packed in way too much of three kinds of cheese,” the banner pitches its sheer volume as a self-declared selling point.

While the post text lists both the “Demi-glace” and “Umatoma” sauces on equal footing, the product name printed in the lower right of the banner reads “Set Meal of Overflowing Three-Kind Rich Cheese-Filled Demi-glace Hamburg Steak,” narrowing the visual spotlight to the Demi-glace version alone. A small photo of the set meal plating (rice, the hamburg steak on its teppan, and miso soup) is included at the bottom of the banner.

The Two Sauce Lines and Their Prices

The two sauce lines highlighted in the post, “Demi-glace” and “Umatoma,” correspond to the pricing structure that was previewed earlier in an official announcement dated May 28.

Sauce Line	Set Meal Price	Rice Set Price
Overflowing Three-Kind Rich Cheese-Filled Demi-glace Hamburg Steak	1,090 yen	990 yen
Overflowing Three-Kind Rich Cheese-Filled Umatoma Hamburg Steak	1,180 yen	1,080 yen

The Umatoma line is priced 90 yen higher than the Demi-glace line. Adding the “+ egg (omelet)” and “+ cheese topping” options brings the lineup to four variations across two set types (set meal / rice set), for 12 variations in total, and the rollout effectively replaces the standard Hamburg Steak with Demi-glace Sauce line, which received a discontinuation notice on May 26 (for full pricing across all variations and details on the succession, see the May 28 launch announcement article).

Timing Matches Past New-Menu X Announcements Exactly

Matsuya’s official X account has kept up a practice of posting a preview a few days before each new menu item’s release. Lining this up against recent examples shows a routine in which both the posting day/time and the release day/time match exactly every time.

Release Date	Item	Official X Announcement	Interval to Release
June 2 (Tue), 10 a.m.	Overflowing Three-Kind Rich Cheese-Filled Hamburg Steak (this article)	May 29 (Fri), 6 p.m.	3 days, 16 hours
May 19 (Tue), 10 a.m.	Set Meal of Grilled Thick Pork with Chimichurri Sauce	May 15 (Fri), 6 p.m.	3 days, 16 hours
May 5 (Tue), 10 a.m.	Taco Rice	May 1 (Fri), 6 p.m.	3 days, 16 hours
April 7 (Tue), 10 a.m.	Umatoma Cheese Beef Bowl	April 3 (Fri), 6 p.m.	3 days, 16 hours

All four of the most recent new-menu launch announcement posts have followed the same rhythm: “announced Friday at 6 p.m., released Tuesday at 10 a.m.” The interval, three days and 16 hours before release, is fixed down to the minute, suggesting a structure in which awareness is built on X over the weekend before the item launches on a weekday morning.
