Daiei redesigns its corporate logo, marking its role as Aeon's core Kansai supermarket business

Daiei Co., Ltd., the Osaka-based supermarket chain wholly owned by Aeon Group, is redesigning its corporate logo from August 2026, the company said in a release dated 17 July. It is the first identity change since Daiei's merger earlier this year with fellow Kansai chain Kohyo Co., Ltd.

Kohyo was absorbed into Daiei in March 2026, an integration the company described as the two chains becoming one after previously separate histories. Despite operating under different names, Daiei said, both businesses had held to the same founding principle since their creation: okyakusama no tame ni (for our customers). The rebrand, the company said, is meant to carry that value forward while signalling the newly combined operation's ambition to create new value.

According to the release, the new mark is built around two ideas: that unchanging customer-first ethos, and Daiei's position as Aeon Group's core operating company for the Kinki (Kansai) region, tasked with creating new value from the region and opening up new eras for it. The design carries specific symbolism, Daiei said: a diagonal, arc-shaped motif in the upper right, likened to a rainbow, is meant to suggest upward momentum and growth while also evoking the shape of the letter D, representing what the company describes as the tomorrow it is changing toward. The mixed capitalisation of 'Daiei' — an uppercase D against a lowercase a — is meant to depict people facing one another: staff, customers, the community, business partners. A distinctively styled lowercase i, meanwhile, is meant to suggest people gathered together.

A corporate identity refresh is usually the last step of an integration rather than the first: companies tend to wait until systems, stores and staff are genuinely knitted together before putting one face on the result, so doing this roughly four months after the Kohyo merger closed reads as Aeon judging that integration largely done. What is more telling is which name survived. Rather than fold both chains into the Aeon or Aeon Style banners it uses elsewhere in the country, Aeon kept Daiei's own name as the identity for the combined Kansai business — and, per the release itself, elevated it to the explicit rank of the group's regional core. That reads as Aeon judging Daiei's decades of brand recognition in its home market worth more than folding it into a shared national banner.

The choice looks sharper set against how Aeon treats former Daiei sites elsewhere. floortok reported separately this month on the reopening of a 44-year-old former Daiei store in Shin-Matsudo, Chiba — back in business, but as an Aeon Style food-and-drug store, with no Daiei signage at all. Put the two together and Aeon's regional playbook comes into view: in Kanto, ageing Daiei real estate is being absorbed into Aeon's own store banners; in Kansai, where Daiei began and where Aeon has just added a second regional chain beneath it, the Daiei name itself is being refreshed and pushed forward as the group's flagship identity. Whether that split holds, or the enlarged Daiei eventually gets folded into a single national brand too, is the next thing to watch in Aeon's slow reorganisation of Japan's regional supermarket sector.
