Hanamaru Udon sells 1kg hiyashi tantan

Hanamaru Udon is doing the giant-food thing, but this one is less random stunt and more menu strategy. On May 12, the chain said it will start selling “Baku Tantan” — a roughly 1kg cold tantan udon bowl with about 340g of meat — across Japan from May 13 through June 3. The bowl lands at the same moment Hanamaru is opening a meat-focused concept shop in Tokyo’s Akasaka district. Basically, the company is using one oversized bowl to advertise a broader idea: udon can be a heavy, protein-forward meal, not just a light cheap one. ### What exactly is Hanamaru selling? “Baku Tantan” is a supersized version of Hanamaru’s already popular cold tantan udon. The company says the bowl weighs about 1kg in total and includes about 340g of meat. It goes on sale May 13, 2026, at Hanamaru Udon stores nationwide, with some exceptions, and the planned run lasts until June 3. Medium is ¥1,380 and large is ¥1,600, and Hanamaru says this one is dine-in only. (hanamaruudon.com) ### Why base it on hiyashi tantan? Because this is already one of Hanamaru’s proven hits. The chain says its “Hiyashi Tantan” line has passed 5 million cumulative servings since 2019. That matters — the company is not inventing a weird flavor to get attention. It is taking a menu item customers already know, then pushing volume and meat hard enough to make it feel new again. (hanamaruudon.com) ### What changed this year? The big shift happened before the 1kg bowl. On April 23, Hanamaru moved “Hiyashi Tantan” from a summer-only limited item to a spring-through-fall regular seasonal offering. The lineup includes white sesame tantan, soft-boiled egg sesame tantan, and pork-shabu sesame tantan. So the giant bowl is not a standalone launch — it is an escalation inside a menu platform Hanamaru is clearly trying to grow. (hanamaruudon.com) ### Why all the meat? Because Hanamaru is testing a different identity for udon. The company is reopening its Akasaka Ichitsugi-dori shop on May 13 as “Hanamaru Udon Niku-ten,” a meat-specialized concept store. That format started in Kagawa in August 2025, and Hanamaru is now bringing it to Honshu for the first time. The message is pretty clear: there is demand for udon that competes with rice bowls and ramen on heft, not just price or speed. (hanamaruudon.com) ### Is this just for one Tokyo store? No — and that is the useful part. The meat-focused store is a Tokyo one-off concept, but “Baku Tantan” is going nationwide, aside from some excluded locations. Hanamaru is using a local store relaunch as the headline event, then attaching a national limited-time product to it. That gives the company a way to test a bigger brand direction without waiting for more concept stores to open. (hanamaruudon.com) ### Why make it dine-in only? Probably because a 1kg cold udon bowl is messy operationally. Hanamaru’s release says the giant bowl is for in-store eating only, even though its regular cold udon lineup is available for takeout. That suggests the company wants control over presentation, portion integrity, and maybe just the chaos factor. A bowl this big is part meal, part visual object. (hanamaruudon.com) ### So is this a gimmick or a real business move? It is both, but the business move is the important part. Chains use oversized items to get attention all the time, but Hanamaru has lined this one up with three concrete moves: a meat-specialized store, a longer selling season for hiyashi tantan, and a flagship item built from a product that has already sold 5 million servings. That is not random menu theater. That is a chain trying to widen what customers think udon is for. (hanamaruudon.com) ### Bottom line? The 1kg bowl is the hook. The real story is Hanamaru trying to turn a seasonal favorite into a bigger, meatier growth lane — and using one absurdly large bowl to make that shift obvious. (hanamaruudon.com)
