(ドムドム) The story behind this trend in Social Media today
02-10-2026
I’ll look up what “(ドムドム)” refers to in today’s social-media chatter.The spike looks tied to a business deal reported today. I’ll pull the details.Today’s social-media chatter around ドムドム is about an ownership deal announced on October 2, 2026: the operator of the Nagoya-based ramen chain Sugakiya has taken Dom Dom Hamburger’s company into its group.Dom Dom is Japan’s oldest hamburger chain in the usual sense of the term. It opened in 1970 under the supermarket group Daiei, a year before McDonald’s first Japanese store. The name comes from Daiei’s old slogan about selling good things “dondon” (steadily) cheap; because “Dondon” was already trademarked, it became Dom Dom. Its longtime mascot is an elephant, Domzo-kun, meant to feel approachable.At its peak it had more than 400 stores, riding Daiei’s national expansion. Competition and store closures later cut it to a few dozen locations, and it was often called an “endangered” chain. A turnaround firm took the brand in 2017. Under president Shinobu Fujisaki it stopped trying to copy the big chains and leaned into odd, highly photographable limited burgerswhole crab, nearly all lettuce, tall vegetable tempura stacks, and similar one-off itemsplus character goods, pop-ups, and collaborations. Those items repeatedly went viral. Goods sales grew into a meaningful share of revenue, stores stabilized around the high twenties, and same-store sales rose for a long stretch. A first overseas shop opened in Taiwan in 2025.In January 2026 the company did a management buyout, with Sugakiya’s parent among the new investors and Fujisaki remaining the largest shareholder and president, saying she wanted to protect what made Dom Dom distinctive. On September 30, 2026, Sugakiya’s parent bought additional shares and, on October 2, announced that Dom Dom is now a group company. Fujisaki stays on as president and keeps a stake.The stated logic is practical. Sugakiya runs roughly 300 stores, mostly in the Tokai region, and is aiming for a much larger chain, including a return to the Kanto region after about twenty years. It wants Dom Dom’s experience with takeout, merchandise, and social-media marketing. Dom Dom, still small and regionally uneven, gains a partner with store-operation scale and a stronger base in central Japan. Online reaction has mostly been surprise that a cheap-ramen chain now sits over the quirky burger brand, jokes about possible cross-regional stores or menu mashups, and relief that the current president is staying.
