The Identity of the 'Mystery Cup' Spotted in Matsuya Official's Twice-cooked Pork Set Meal Taste Test

On the night of July 14, 2026, Matsuya’s official X account (@matsuya_foods) reported having tasted the limited-time ‘Twice-cooked Pork Set Meal,’ which launched that same day. The post went up just after 8 p.m. on launch day, accompanied by a photo of a plate with meat, vegetables, and sauce all tossed together, along with the comment: ‘The meat, vegetables, and sauce go together perfectly!’

Choosing the Soft-boiled Egg Side Dish: What’s on the Plate

The Twice-cooked Pork Set Meal lets diners choose either Kimchi or Soft-boiled Egg as a side dish. The post reveals the choice with the line, ‘I went with soft-boiled.’

In the photo, slices of pork coated in white sesame seeds mingle with cabbage, green pepper, onion, and julienned carrot, all bound together by a thick, reddish-brown sauce. The dish sits on one of Matsuya’s colorful polka-dot plates. Rice and a bowl of runny Soft-boiled Egg sit at the upper left, alongside a small container of sauce apparently meant for adding extra, with Miso Soup served on the right. In the lower left of the frame, an overlay of Macky & Yakky and the words ‘Itadakimasu’ suggests this shot was taken just before the meal began.

From Announcement to Launch to the Commemorative Campaign

Ahead of the taste-test report, an official X post at 6 p.m. on July 10 had announced: ‘Twice-cooked Pork goes on sale Tuesday, July 14, at 10 a.m.’ At exactly 10 a.m. on launch day, July 14, the official X account also announced a Follow & Repost Campaign to mark the release, offering 30 winners a chance to receive 1,000 Matsuya Points each via lottery (entries closed July 20). The evening taste-test report serves as the capstone of a launch promotion that unfolded over four days — announcement, launch commemoration, and taste-test report.

Pricing and the Limited-time Set Meal Lineup

Twice-cooked Pork comes in three sizes — Only at 680 yen, Set Meal at 880 yen, and Double at 1,370 yen. The menu splits by side dish (Kimchi or Soft-boiled Egg), but pricing is the same across both. It appeared in the Limited-time section of Matsuya’s official website on the morning of July 14. The Set Meal follows Matsuya’s standard format, served with rice and salad.

Recently, the Stir-fried with Ginger Soy Sauce Set Meal (850 yen) and the Yatara Japanese-style Hamburg Steak Set Meal (1,180 yen), both of which debuted on July 7, remain on the menu, continuing a lineup with several limited-time set meals side by side. At 880 yen, the Twice-cooked Pork Set Meal falls within the price range of this group of limited-time set meals.

The ‘Mystery Cup’ in the Background

The post closes with an offhand mention of a cup visible in the background: ‘Hey, what’s that mystery cup back there…?’ A closer look at the photo reveals a ‘Soy Milk Pudding’ label on the side of the cup — apparently the Japanese-style sweet, priced at 180 yen tax included, that also joined the side menu on July 14. It’s a cup dessert served with kinako (roasted soybean flour) and kuromitsu (black sugar syrup), making its debut on the same day as the Twice-cooked Pork Set Meal. The official account itself framed the pairing of a Chinese-style set meal with a Japanese-style dessert as a playful little riddle.
