Calpis was first introduced way back in 1919. The first marketing campaign claimed Calpis Soda looks like the Milky Way. Calpis comes in many forms: carbonated (Calpis Soda), uncarbonated (Calpis Water) and Calpis Concentrate.
The concentrate version was most popular before WWII because it kept well without refrigeration.
These days, Calpis has hundreds of varieties that come and go each year. It is also co-branded with other Japanese soft drink and candy brands.
Calpis has many flavours.
