MUJI, CAINZ and Daiso each win 2026 Good Design Awards for private-brand products

The Japan Institute of Design Promotion named its 2026 Good Design Award winners on October 15, the 70th edition of an award founded in 1957, and Japan's biggest value-retail chains for the home all feature on this year's list: Ryohin Keikaku Co., Ltd. (MUJI), CAINZ Corporation and Daiso Industries Co., Ltd. each said their own products had been recognised, while East Japan Railway Company's group separately picked up six awards of its own.

MUJI's refill detergent makes the top tier

Ryohin Keikaku said three of its products and spaces won a 2026 Good Design Award: its Diluted Detergent Series (希釈洗剤シリーズ), which the jury placed in the award's Best 100 -- the programme's top tier -- its Iidabashi First Tower headquarters, run as a "live office" testbed, and a Board Furniture T-Leg office-furniture line built from domestic timber, the company said.

The detergent line sells a concentrated cleaning formula in a small pouch that the buyer dilutes with water in a dedicated bottle, which Ryohin Keikaku said is meant to cut the bulk and weight of carrying and storing detergent at home -- a direct answer to the industry's drift toward ever-larger refill containers. The jury's comments, carried in the release, praised the packaging and naming for communicating the dilution step intuitively. The Iidabashi office, the company said, is a working floor that doubles as a design testbed, where staff behaviour feeds directly back into material and furniture choices, including the renewed and recirculated furniture the jury cited in the T-Leg award.

CAINZ, fifteen years running

CAINZ Corporation said six of its private-brand products won 2026 Good Design Awards, extending a run of consecutive wins to fifteen years: a pop-up tabletop barbecue grill, a silicone food cover designed to replace plastic wrap, a shoe hanger that works hung or standing, a magnetic broom-and-dustpan set that clips to an entrance door, a work-glove line cut in ten sizes for Japanese hand shapes, and a 3.7kg wheeled carrier rated to 100kg that folds flat into a cart, the company said. Prices range from ¥248 for the gloves to ¥5,980 for the carrier.

None of the six costs more than ¥6,000, and that is rather the point of fifteen consecutive years of wins: CAINZ is using a national design award to argue that a home-improvement chain's everyday private-brand shelf can carry the same design credibility department stores built their house labels on.

Daiso adds two, one still unreleased

Daiso Industries said two of its products won 2026 Good Design Awards: a double-sided, assemble-it-yourself triangular scratching pad sold under the DAISO brand, which the company listed as not yet on sale, and a Setouchi olive skincare range -- a face wash, a face mask and a lip balm -- sold under its Standard Products by DAISO label and already in stores, the company said.

JR East's six, led by a freight Shinkansen

East Japan Railway Company's group said separately that six of its projects won 2026 Good Design Awards, led by a cargo-dedicated Shinkansen service run jointly with group company JR East Logistics, and "JAL de Hakobyun" (JALデはこビュン), a rail-to-air freight link with Japan Airlines that the jury's comments cited for delivering live Echizen crab to Taiwan the same day it was caught. The remaining four covered a station-operations app built with Nebra Inc., two mixed-use property conversions, and a 25-unit condominium in Tokyo's Todoroki district, the group said.

Four companies with very different businesses, one shared signal: in a market where department stores built their design reputation one house label at a time, the Good Design Award's winners list now reads as much like a map of the value aisles and the station concourse as it does the department-store floor -- and for MUJI, CAINZ and Daiso, a once-a-year, government-affiliated award has become cheap, repeatable proof of exactly that.
