Mos Burger March 17 giveaway
Mos Burger ran a one‑day March 17 campaign in Japan for a Cheese Bacon Teriyaki Burger and offered a promo giveaway to 100 winners who reposted the campaign, generating thousands of likes and reposts on social Mos Burger campaign.
The campaign’s official X post drew specific engagement figures — 1,305 likes and 1,194 reposts — and the hashtag "#モスからチーズベーコンテリヤキ" trended on X. (whytrend.jp) Mos Burger scheduled the Cheese Bacon Teriyaki Burger for nationwide release on March 18, 2026 at a price of ¥590, with the item slated as a limited-time offering through mid‑May. (j-cast.com) The company described a reformulation of its teriyaki sauce that swaps white sugar for sanontō (三温糖) and apple paste and adds soy moromi and bonito for greater umami as part of the chain’s first teriyaki refresh in four years. (oricon.co.jp) The launch includes two new variants: the quantity‑limited "とろったまベーコン テリヤキバーガー" and the period‑limited "チーズベーコン テリヤキバーガー," both listed at ¥590, while the reworked standard Teriyaki Burger is priced at ¥470. (weekly.ascii.jp) Mos Burger also planned a post‑launch receipt promotion running March 18 at 15:00 through March 31 at 23:59 that invites LINE entries for a points gift with 500 winners named in the campaign rules. (mos.jp) Mainstream outlets covering the rollout included Oricon, J‑CAST and ASCII, which all reported the March 18 release, the teriyaki recipe changes, and the introduction of the two bacon‑and‑egg/cheese variants.
