Calpis Day (Karupisu no Hi)

What Is Calpis Day?

July 7 is "Calpis Day." It commemorates July 7, 1919 (Taisho 8), when the lactic acid bacteria beverage "Calpis" was first sold in Japan. Since it launched on Tanabata (the Star Festival), Calpis's refreshing, cool image has become closely linked with this day, and it's now widely recognized as an anniversary.

Why Was It Launched on July 7?

Calpis founder Kaiun Mishima reportedly considered Tanabata — "the day wishes come true" — to be especially auspicious, and chose to align the launch date with it. It was also timed to coincide with the start of summer, as a drink perfectly suited to the hot season.
