Having its headquarter in Shinjuku - Tokyo, Isetan is a leading corporate group in Japan's retailing industry and renown for its unique ranges of merchandise with high-quality service department store, domestically and internationally.

Isetan has been a watchword for creativity and ingenuity since it established over a century ago in 1886. Isetan always aim for high customer's satisfaction and is devoted to provide customers with the best and most innovative products. In the 1890s and early 1900s, Isetan obtained a high reputation for fashionable kimono designs and obi sashes after which Isetan's name became associated with the latest in fashion apparel.

When the market was shifting from tailor-made clothes to ready-to-wear clothes in the mid-1950s, a new off-the-rack sizing system revolution was introduced to suit the Japanese female figure. In 1965, Isetan and other major department stores succeeded in establishing a new uniform size-numbering system for woman's apparels. And this had remained in Japan until today. With continuous focus on developing innovative sizes, Isetan also launched several specialty shops namely "Lady Clover" specially for larger women, "Strawberry" and "Young Clover" specially for petite sizes. Today, Isetan's Size Network has broadened its focus to accommodate not just for women but also for men's apparel, furniture, household items and food.

In 1968, Isetan proved themselves as a trend innovator when they opened Men's Annex, the 1st department store specially for men (which was one of the only few in the world at that time). The Men's Annex gained many new customers when men's fashion became popular and Japanese men began to show more individuality in their clothes.

In 1972, Isetan opened its first overseas department store in Singapore and was among one of the first Japanese retail group to enter the Asian market. With the continuing expansion plan, Isetan has gradually established its business in Kuala Lumpur, Kaoshiung, Bangkok, Shanghai and Tianjin. To support the international aspects of the merchandising, Isetan also set up its overseas representative offices in New York, Paris, Milan and Hong Kong - fashion capitals of the world.

In 1990, Isetan opened its 1st department store in Kuala Lumpur in Lot 10 shopping centre. With "Customer First" as guiding principal in all aspects of serving customers, Isetan Kuala Lumpur successfully launched a card member service club to promptly respond to various customer's needs. Its international designer boutiques at the upper level was among the 1st of its kind in the country's fashion retailing.

On May 30, 1998, Isetan Kuala Lumpur opened its flagship store at Suria KLCC, situated next to the Petronas Twins Towers, (the tallest building in the world at that time). With 5 floors of exciting merchandise catering for the entire family and occupying quarter million square feet retail space, Isetan KLCC store has become a major landmark in the retail industry.
