OK Umeyashiki

OK Umeyashiki (オーケー 梅屋敷店) is a discount supermarket store located at 6-5-6 Omorinishi, Ota-ku, Tokyo, operated by OK Corporation (オーケー株式会社), one of Japan's best-known discount grocery chains. The store opened on 25 May 2018 and trades under the OK banner, which is built around the management philosophy of 'High Quality, Everyday Low Price' (高品質・Everyday Low Price). It is a leased (賃借) outlet with a sales floor of roughly 956 square meters (about 289 tsubo) and 21 parking spaces, and it sits about a four-minute walk from Umeyashiki Station and a five-minute walk from Omorimachi Station on the Keikyu Main Line. The store carries a full supermarket assortment: groceries, daily necessities, liquor, delicatessen items, sushi, pizza and bakery goods. Its opening hours are 08:30–21:30 on both weekdays and weekends/holidays. Payment options are broad and include cash, major credit cards (JCB, VISA, MasterCard, AMEX, Diners, UnionPay), Japanese transit IC cards (Suica, PASMO, TOICA, ICOCA, Hayakaken, nimoca, Kitaca), e-money (iD, QUICPay), smartphone payments (PayPay, Rakuten Pay, auPAY, d Payment, Smart Code, Merpay) and Chinese QR payments (WeChat Pay, Alipay+). A signature feature of the OK format is the OK Club membership card: when presented, members receive a discount equivalent to 3/103 of the pre-tax price on food items (excluding alcohol), a mechanism OK introduced to offset the consumption tax for shoppers. This discount does not apply to tax-free purchases or to non-cash payment methods. The store also participates in OK's chain-wide official social media channels, which share product information and new-store news. OK Umeyashiki is one of many locations in OK Corporation's store network, which spans the Tokyo 23 wards and surrounding areas as well as Kanagawa, Chiba, Saitama, Osaka and Hyogo. The parent company traces its origins to 1958, when it began as the retail division of Okunaga Shoten, and was incorporated as OK Corporation in 1967. OK Corporation remains a private company and is known for its aggressive growth targets, its own logistics centers, and its Everyday Low Price positioning.

OK Umeyashiki is a store of OK Corporation (オーケー株式会社), a Japanese discount supermarket chain whose roots go back to June 1958, when it was founded as the retail division of Okunaga Shoten (岡永商店). In September 1964 the business introduced a computer-based merchandise management system, and in September 1967 it was separated from Okunaga Shoten and incorporated as OK Corporation with capital of 70 million yen. The company absorbed Tokyo Supermarket in October 1971, and in May 1975 it developed and test-operated what it described as the world's first unmanned supermarket together with Japan's Ministry of International Trade and Industry. A turning point came in April 1986, when OK launched a fundamental management reform, adding 'Everyday Low Price' to its existing basic policy of 'High Quality, Good Value'. In 1987 it conducted market research for the Japanese market together with France's Carrefour. When the consumption tax was introduced in April 1989, OK began offering a discount of 3/103 of the pre-tax price on food, effectively eliminating the tax burden for shoppers, and it also introduced paid shopping bags that same month. In March 1996 the company publicly set a management goal of 'challenging 30% annual growth'. In November 2001 it abolished special-sale flyers in favor of a product-information paper to reinforce its 'High Quality, Everyday Low Price' policy, and in 2002 it began setting sales budgets at a uniform 110% of the previous year for all stores and departments. The OK Club membership program was launched in November 2006, with the 3/103 food discount becoming a members-only benefit; membership was then about 800,000. OK Corporation continued to refine its operations through the 2010s and 2020s, building its own ambient-temperature and frozen logistics networks and pursuing a long-term goal of growth without borrowing. For the fiscal year ended March 2025, the company reported sales of 686 billion yen, up 110.1% year on year, with existing-store sales up 105.4%. It set a budget of 739.7 billion yen for the fiscal year ending March 2026. In 2024 it established its own store logistics network for frozen goods such as frozen foods, ice cream and delicatessen ingredients, purchasing at center-delivered prices just as it does for ambient goods. OK Umeyashiki itself opened on 25 May 2018 in the Omorinishi district of Ota-ku, Tokyo, near Umeyashiki and Omorimachi stations on the Keikyu Main Line. It is a leased store with a sales floor of about 956 square meters and 21 parking spaces, and it operates from 08:30 to 21:30 daily. Like other OK stores, it offers the OK Club member discount on food (excluding alcohol) and accepts a wide range of payment methods, including cash, credit cards, transit IC cards, e-money, smartphone payments and Chinese QR payments.
