Matsuya’s official X account (@matsuya_foods) posted at 8:41 PM on May 26, 2026, reporting that it had eaten the store-limited menu item ‘Black Carbonara Sauce Hamburg Steak’ (set meal, 980 yen), which went on sale at 10 AM today. The post opens with “This week is ‘Test Sale Festival’!!” and positions this Black Carbonara as the first installment. Having the official account feature a new menu item on its very first day on sale is the third such case in May, following the Taco Rice on May 5 and the Chimichurri Thick-Cut Pork on May 19.

Original Post

This week is ‘Test Sale Festival’!!

First up, we tried the “Black Carbonara Sauce Hamburg Steak” (╹◡╹)

Black carbonara!? If that’s what you’re thinking, please give it a try.

#Matsuya #WhileSuppliesLast #SorryIfItsSoldOut

The opening “we tried” with the (╹◡╹) emoticon has become a regular feature of eating-report posts since April. The post follows a five-part structure: a weekly declaration, an introduction of the first item eaten, a line that anticipates readers’ surprise and urges them to try it, a store search link, and hashtags. Compared with earlier posts, it adds one new opening line announcing a weekly theme.

“This Week Is ‘Test Sale Festival’”: A Weekly Event Declaration

The first line, “This week is ‘Test Sale Festival’!!”, is the first “weekly event declaration” style among the eating-report posts since May. Test sales, which had previously been mentioned only one at a time, such as “currently on test sale” and “I get excited during weeks with test sales,” are now explicitly framed as a ‘festival’ for the week.

Date	How test sales were mentioned
May 6	Post body explicitly says “Yatarazuke Beef Bowl, currently on test sale”
May 14	Post body says “The person running this account is a Matsuya geek, so I get excited during weeks with test sales”
May 26 (this post)	Opens with a weekly event declaration: “This week is ‘Test Sale Festival’!!”

The hashtags #WhileSuppliesLast and #SorryIfItsSoldOut also emphasize the limited nature of test sales, the same pattern as the May 14 post about eating the Okra and Grated Domestic Yam Paste Beef Bowl.

“Black Carbonara!?”: Anticipating Readers’ Surprise

The third line, “Black carbonara!? If that’s what you’re thinking, please give it a try,” puts into words the confusion readers may feel on seeing the product name (the oddness of a carbonara that looks black) and then urges them to try it anyway. The photo of the meal has a Macky stamp and a speech bubble reading “Seriously?!” composited onto it, so the post’s “Black carbonara!?” and the image’s “Seriously?!” echo each other, and the communication is built around the surprise of a first encounter.

In the promotional poster, the product appears as a pitch-black hamburg steak topped with a yellow egg-yolk sauce, surrounded by Parmesan cheese and coarsely ground pepper. In the photo of the meal, the same black carbonara hamburg steak is served on a white round plate bearing the Matsuya logo, arranged as a set meal with rice, cabbage salad with corn, and wakame miso soup.

Product Information (This Morning’s Store-Limited Addition)

‘Black Carbonara Sauce Hamburg Steak’ is one of three items listed this morning, May 26, 2026, at 10 AM as store-limited menu items. The top of the promotional poster carries the line “On sale at limited stores ahead of a nationwide rollout this winter,” making clear that the store-limited sale is a test-marketing stage with an eye toward a winter nationwide launch.

Item	Details
Product name	Black Carbonara Sauce Hamburg Steak Set Meal
Price	980 yen (set meal)
Release	Tuesday, May 26, 2026, 10 AM
Sales category	Store-limited (70 stores)

Tagline	“Matsuya’s carbonara turns black” / “Parmesan cheese and coarsely ground pepper burst with flavor: ultra authentic”

The masked “Black ○○○” was a teaser dropped five days earlier in a 7:27 PM post on the official X account on May 21: “Next week, apparently you may or may not be able to eat Black ○○○ at limited stores…!?” Its identity was revealed this morning with the addition of three store-limited items, as ‘Black Carbonara Sauce Hamburg Steak.’ With tonight’s eating report, the official account has carried it all the way through to actually eating it.

First ‘Hamburg Steak’ Eating Report of May

Here is a breakdown of the eating-report posts since May by the category of the menu item eaten. This is the first time a hamburg steak item has been the subject of an eating report.

This is the 11th eating-report post of May. They have so far covered a wide range of categories, including “beef bowl,” “curry,” “bowl,” and “pork set meal,” but this is the first time for the hamburg steak category. In keeping with the ‘Test Sale Festival’ declaration, the other two items added the same day (the Stew Hamburg Steak Set Meal and the Yulinji Set Meal) are likely to be featured in eating reports later this week.
