Quick Answer
50 Lan is a Taiwanese brand, founded in 1994 in Tainan by Ma Shao-wei. What does the name mean? It comes from the Japanese surname Igarashi (written with the characters for “fifty” and “storm”), which the founder spotted in a Japanese magazine and liked because it sounded good and was easy to remember. Its signature “50 Lan No. 1” is Four Seasons Spring tea with tapioca pearls, large boba and nata de coco. The first model store (Xinxiao store) opened in Tainan in 1997. According to Wikipedia, 50 Lan in Taiwan is divided into four operating regions, Tainan (company-run), North, Central and Kaohsiung, with about 600 locations nationwide. The often-asked-about KOI Thé was founded in 2006 by the founder’s sister Ma Ya-fen and went overseas from Singapore in 2011; mainland China’s Yi Dian Dian (also written 1Dian Dian) was started by 50 Lan’s Northern region operator and has no capital, staff or ownership link to 50 Lan in Taiwan.
