NUMAZU, November 8, 2026 — A pop-up restaurant where getting the wrong order is the point opened for a trial run in this Shizuoka Prefecture city on November 1. The concept, which began in 2018, pairs seniors living with dementia with existing eateries to reframe service errors as lessons in patience.
Origins and Philosophy
The Japanese name, Chumon wo Machigaeru Kamoshirenai Ryori-ten, translates to “Restaurant where it’s OK to get customers’ orders wrong.” It started as a pop-up concept partnering with existing restaurants, not as a permanent venue. The mission, organisers say, is fostering awareness and consideration toward people with dementia rather than simply creating employment. Operating profits are not a priority; the project accepts online donations to sustain its work.
Recent Events in Numazu and Matsuyama
On November 1, a trial event at Harmony Kitchen in Numazu’s Ooka district featured four women in their 70s to 90s as waitstaff. The initiative was organised by a committee including Riichiro Iida, 50, a construction company owner whose father and father-in-law have dementia. Chef Mitsuo Hashimoto, 56, prepared a course meal for 11 diners in the first session. Iida told guests: “Even if a different dish arrives than the one you ordered, just think, ‘That’s OK,’ and enjoy it in that spirit.”
Earlier, on September 21 — Respect for the Aged Day and World Alzheimer’s Day — a pop-up at Tenryu Ramen in Matsuyama, Ehime Prefecture, deployed four participants aged 78 to 88. Diners included the daughter and granddaughter of one waitress. A father of four at the event noted: “If we took our time and listened and spoke patiently, we could understand each other.” One waitress said she was “really happy to get to see so many people and talk with them.”
Community Drivers and Participant Voices
Iida launched the Numazu project from personal experience with his family. In Matsuyama, the partnership with Tenryu Ramen anchored the event in a local institution. At Harmony Kitchen, participants already prepare boxed lunches and side dishes regularly. One Numazu waitress, a former school-lunch cook, said the work brought back memories. Another admitted initial nerves but added: “It went well in the end.”
Next Steps
Numazu organisers plan a full-scale public event around summer 2027. Iida said: “We are exploring the best way to run the project, and we hope to improve it ahead of the main event next year. We hope to create a place where people can laugh together, even when small mistakes happen.”
