#Matsuya #WhileSuppliesLast #SorryIfItsSoldOut

The opening emoticon “(╹◡╹)” is the one that has become a fixture in the “eating report” posts since April. “Another test-sale menu item today” is an opener signaling the continuation of the “This week is the ‘Test Sale Festival’” declared the previous day. After quoting the product name, the post’s midsection poses the question “Has there ever been a longer product name than this…?”, inviting readers to share past examples.

Product Name Runs 27 Characters, Among the Longest in Recent Matsuya Menus

The “Hamburg Steak in Rich Umami Stew with Mushroom Duxelles Set Meal” carries a 27-character name in the original Japanese. Compared with past store-limited and limited-time menu items, its length stands out.

Product Name	Characters (JA)	Category
Hamburg Steak in Rich Umami Stew with Mushroom Duxelles Set Meal (this item)	27	Store-limited
Chunky Stewed Tandoori Chicken Loin Katsu Curry and Rice	23	Store-limited
Yatarazuke Beef Bowl Yatarazuke Hamburg Steak Set Meal	20	Store-limited
Set Meal of Grilled Thick Pork with Chimichurri Sauce	19	Limited-time
Half-and-Half Beef Umatoma Hamburg Steak Set Meal	18	Limited-time

Among Matsuya’s recent new products, this 27-character name ranks among the longest. It strings together the ingredient (mushroom duxelles), a preparation modifier (“with”), descriptors (rich umami / rich), the main dish (stew hamburg steak), and the format (set meal) all in one continuous run — the result of packing the “Bistro Matsuya” series’ “bistro style” straight into the product name.

The “Bistro Matsuya Revival” Announcement

At the top of the promotional poster, a large “BISTRO MATSUYA / Bistro Matsuya Revival” logo is displayed, explicitly signaling the return of the past series. The poster copy reads, “Umami-packed mushroom duxelles and a jet-black sauce of cacao x Maruya Hatcho Miso. A Matsuya-style bistro masterpiece intertwined with meat juices,” with the sauce built from “a jet-black sauce of cacao x Maruya Hatcho Miso.” In the eating-report photo, the hamburg steak sits on a teppan filled with the jet-black sauce, topped with mushroom duxelles, with a mashed-potato-like white side arranged alongside. A Macky & Yakky stamp and an “Oishii (delicious)” speech-bubble graphic are composited into the lower left of the image.

The Flow of May’s “Eating Report” Posts

The “eating report” posts have continued at a near-daily pace since May, and this stew hamburg steak marks the 12th installment. As a “Test Sale Festival” week, it’s the second installment, following the previous day’s Black Carbonara post.

Date	Menu Item Eaten	Category
May 2	Salt-based Green Onion Bowl	Bowl
May 3	Chunky Stewed Tandoori Chicken Loin Katsu Curry and Rice	Curry (Store-limited)
May 4	Iburigakko Beef Bowl	Beef Bowl (Regional)
May 5	Taco Rice	Other
May 6	Yatarazuke Beef Bowl	Beef Bowl (Test Sale)
May 7	Hiyajiru / Chicken Nanban	Regional (Miyazaki)
May 13	Butter Chicken Curry and Rice	Curry
May 14	Okra and Grated Domestic Yam Paste Beef Bowl	Beef Bowl (Test Sale)
May 18	Beef Bibim Bowl	Bowl
May 19	Set Meal of Grilled Thick Pork with Chimichurri Sauce	Set Meal (Pork)
May 26	Hamburg Steak with Black Carbonara Sauce	Set Meal (Hamburg Steak, Test Sale)
May 27 (this item)	Hamburg Steak in Rich Umami Stew with Mushroom Duxelles Set Meal	Set Meal (Hamburg Steak, Test Sale)

Of the three items announced in the “Test Sale Festival” declaration (May 26) — Black Carbonara, Stew Hamburg Steak, and Yulinji — today’s post checks off the Stew Hamburg Steak. That leaves just one remaining: the “Yulinji Set Meal.”

The “Longer Product Name” Question Is a New Pattern

The latter half of the post — “Has there ever been a longer product name than this…?🤔 If you know of one, please tell us.” — represents a new type of question structure among the “eating report” posts since May.

Date	Question / Reader Engagement Element
May 2 (Salt-based Green Onion Bowl)	“What toppings do you like?” (topping question format)
May 18 (Beef Bibim Bowl)	“Which era’s Bibim Bowl do you prefer?” (nostalgia poll)
May 23 (Quiz)	“Which one is Amakurisotsu’s Touchin?” (3-choice quiz)
May 27 (this item)	“Has there ever been a longer product name than this…?” (past-example poll)

Following the topping, preference, and quiz formats, the “invite readers to compare past examples” approach has been added as a new pattern. The account manager’s own stance of asking readers to “please tell us” echoes the self-description as a “Matsuya otaku” from the May 14 okra and grated yam post — a similarly casual tone. During Test Sale Festival week, the official account’s distance from its readers has narrowed another notch.
