Why now? The acquisition caps a six-month courtship. Sugakico took a minority stake in DomDom in December 2025, then opened a DomDom branch on the site of a former Sugakiya store in Nagoya's Osu district in July 2026.
During that period the companies shared store-operations expertise, sold collaboration goods, and supported a rebuild of DomDom's back-office functions. Sugakico said the trial convinced both sides that a formal tie-up would deliver significant mutual benefits.
What's the endgame? Sugakico, founded in 1946, has shifted to a new structure for its 80th anniversary and is targeting a 1,000-store chain. It currently runs about 300 outlets. DomDom's strengths in merchandising, marketing, and takeaway give the group a non-ramen, takeaway-focused format that widens its options for new locations.
What else? As a first step toward its 1,000-store goal, Sugakico has decided to bring Sugakiya back to the Kanto region for the first time in roughly 20 years. The company also plans joint openings of both brands in the same commercial facilities next spring.
What changes for DomDom? Little, on the surface. Shinobu Fujisaki stays on as president and keeps a portion of the shares. Sugakico will provide financial backing and multi-store expertise so DomDom can invest more aggressively.
What could go wrong? Sugakico stresses this is not simply about scale. Blending its store network, development muscle, and supply chain with DomDom's free-wheeling product ideas and brand power carries integration risk; both brands rely on distinct, long-standing customer loyalty that heavy-handed consolidation could erode.
The signal: Japan's fragmented restaurant sector is consolidating as established chains hunt for growth beyond their core formats. By pairing a regional ramen operator with a quirky national burger brand, Sugakico is betting that portfolio diversity — not single-format expansion — is the surer path to scale.
