(#モスのNEW月見フォカッチャ発売) What is the story behind this trend in Social Media today?
09-09-2026
The hashtag marks Mos Burger’s upcoming autumn limited item, the new Tsukimi Focaccia with golden cheese sauce, which goes on sale nationwide the next day. The chain first introduced a Tsukimi Focaccia in 2022 as its own take on Japan’s seasonal moon-viewing burgers; the sandwich quickly became an annual fixture, selling more than fourteen million units across four previous seasons. This year’s version keeps the familiar horseshoe-shaped smoked sausage, fluffy focaccia, shredded cabbage, and soft-cooked egg but replaces the long-standing barbecue sauce with a richer golden cheese sauce made from Parmesan, cheddar, egg-yolk powder, and black pepper. A cheese-sauce-only version without the egg is also offered. The change was framed around a “golden moon” theme meant to evoke a luxurious moon-viewing meal and to broaden appeal, especially among younger customers and families. On the eve of launch, social-media users began posting photos of the official promotional images, expressing impatience to try the new sauce, and planning lunch visits for the following day. The combination of a well-liked seasonal product, a visible recipe refresh, and the immediate availability of appetizing official visuals produced a concentrated burst of anticipatory posts the day before the sandwich actually appeared in stores.
