Seiyu GK (合同会社西友, Gōdō-gaisha Seiyū) or Seiyu Group (西友グループ, Seiyū Gurūpu), is a Japanese group of supermarkets, shopping centers and department stores owned by Walmart. Its head office is in Akabane [ja] (赤羽), Kita, Tokyo.[1][3]


The group was established in December 1946, and was formed in 1956 by Seibu Department Stores, a group company of Seibu Railway. In 1980, Seiyu launched its private brand Mujirushi-Ryōhin (commonly known as MUJI outside Japan). MUJI was transferred to the Ryohin Keikaku Company[4] in 1990, and is no longer part of Seiyu.

On December 31, 2003, Seiyu and Walmart signed a partnership agreement in which Walmart would teach global supply chain practices.[5] Numazu, Shizuoka was the site of the first Seiyu store using Walmart methods.[5]

Walmart bought a 37 percent stake in Seiyu in 2002,[6] and according to a company press release,[7] in late 2005, Walmart acquired a majority stake in the company, which it has since increased to 100% ownership in 2008.[8]

Previously, the company had a registered office in Higashi-Ikebukuro, Toshima, Tokyo.[9]

Stores outside Japan[edit]

In addition to its Japanese operations, Seiyu also had department stores operating under its name in Singapore and Hong Kong. The group used to directly operate these stores, but in October 2005, its three Singapore stores were sold to CapitaLand Limited,[10] which transferred them to Beijing Hualian Group later the same year.[11] The group's Hong Kong store in New Town Plaza, Sha Tin was sold to Sun Hung Kai Properties Limited in June 2005,[12] but like the stores in Singapore, continued to operate under the Seiyu name until April 2008. The Singapore stores were then renamed BHG, which stands for "Beijing Hualian Group".
