Bubble tea, also known as tapioca tea, pearl tea, and boba, is one of the few examples of a Taiwanese craze hitting Japan.
Add powdered milk or fresh milk and you get bubble milk tea, which has become a booming product in Japan.
Founder Tu Tsung-Ho claims to have used top quality Taiwanese tea leaves to invent the first cold tea drink.
“We added it not just to milk tea, but also to black tea, green tea, but we discovered that milk tea was the most popular,” said Huang.
Together with other Taiwanese bubble tea brands, like Kaohsiung-based Gong Cha, Chun Shui Tang has appealed to Japanese consumers with customized drinks.
