History
Oishi was founded by businessman Tan Passakornnatee, who opened its first all-you-can-eat sushi restaurant on 9 September 1999. Oishi was successful in tapping the rapidly expanding market for Japanese cuisine, which previously only comprised Japanese expatriates and tourists, and opened it up to the middle class. The company was registered as Oishi Restaurant Co., Ltd. on 5 January 2000, and expanded to include several restaurant chains spanning different price ranges over a course of four years. Tan noticed the popularity of the green tea drinks served in its restaurants, and began to produce them as bottled drinks.
