The special menu item packs three kinds of cheese into the hamburg steak, and the post highlights that customers can choose between two sauces: ‘Demi-glace’ and ‘Umatoma’.

Original Post

Going on sale June 2 (Tue) at 10 AM: “Overflowing Three-Kind Rich Cheese-Filled Hamburg Steak” 🎉

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

Choose from two sauces: “Demi-glace” or “Umatoma”!

Be sure to try it while you can!

The post opens with the release date and product name on a single line, then adds a 🎉 emoji to set the mood. The next two paragraphs present the selling points in order: “three kinds of cheese packed in” and “choice of two sauces.” The closing line is the usual “Be sure to try it while you can.” The “(╹◡╹)” emoticon and the questions and reader-participation elements that had become a fixture in the recent eating-report posts were not used this time, and the post was kept to a simple new-product announcement.

Promotional Banner Puts ‘Overflowing Emotion.’ and the Demi-glace Version Front and Center

The promotional banner attached to the post has the catchphrase ‘Overflowing Emotion.’ in bold black text on a yellow background across the top half, with white circular decorations representing the three cheeses layered over the lettering. A hamburg steak on an iron plate sits in the center, capturing the moment yellow cheese flows out of a vertical cross-section. The hamburg steak is covered in glossy demi-glace sauce, and together with the black band of copy on the left, ‘We packed in too much of the three cheeses.’, the design plays up the sheer volume as a self-declared selling point.

In the post text, the ‘Demi-glace’ and ‘Umatoma’ sauces are listed on equal footing, but the product name at the bottom right of the banner reads “Overflowing Three-Kind Rich Cheese-Filled Demi-glace Hamburg Steak Set Meal,” so the visual focus is on the Demi-glace version. A small photo of the set meal presentation (rice, the hamburg steak on an iron plate, and miso soup) is placed along the bottom of the banner.

Two Sauce Options and Prices

The two sauces promoted in the post, ‘Demi-glace’ and ‘Umatoma’, correspond to the price structure announced in advance in the official news release dated May 28.

Sauce type	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 version is priced 90 yen higher than the Demi-glace version. With the ‘Egg (Omelet)’ and ‘Cheese topping’ options added, there are 4 variants × 2 sets (set meal / rice set), for a total of 12 variations. The item is being introduced as a replacement for the classic Demi-glace Sauce Hamburg Steak lineup, which received a discontinuation notice on May 26 (see the May 28 launch announcement article for all variation prices and details on the successor items).

Timing Identical to Past New-Menu X Announcements

Matsuya’s official X account has kept up the practice of posting a preview a few days before a new menu item goes on sale. Lined up against recent examples, the announcement day and time and the release day and time match exactly, showing a fixed routine.

Release date	Item	Official X announcement	Gap until release
June 2 (Tue), 10 AM	Overflowing Three-Kind Rich Cheese-Filled Hamburg Steak (this article)	May 29 (Fri), 6 PM	3 days 16 hours
May 19 (Tue), 10 AM	Set Meal of Grilled Thick Pork with Chimichurri Sauce	May 15 (Fri), 6 PM	3 days 16 hours
May 5 (Tue), 10 AM	Taco Rice	May 1 (Fri), 6 PM	3 days 16 hours
April 7 (Tue), 10 AM	Beef Bowl topped with Tomato and Cheese	April 3 (Fri), 6 PM	3 days 16 hours

The announcement posts for the last four new-menu releases all followed the same rhythm: announced Friday at 6 PM, on sale Tuesday at 10 AM. The gap of 3 days 16 hours before release is fixed down to the minute, which suggests a structure that builds awareness on X over the weekend before the weekday-morning launch.
