UCC

UCC canned coffee became famous nationwide at the 1970 Osaka Expo and was a huge hit.
The UCC Coffee with Milk from that time is still on sale today and is a symbolic UCC product.
As the name UCC Ueshima Coffee suggests, UCC was founded by Mr. Ueshima, and its origins date back to 1933 when Ueshima Tadao Shoten opened in Kobe.
It seems that it was common in 1933 for a store name to include the president's full name.

Canned coffee is a standard item in drink vending machines.
While the brands stocked vary depending on the vending machine, most brands have canned coffee.
Even if they don't carry cola, canned coffee is often available.

Coffee manufacturers began developing canned coffee commercially in the 1950s. There was likely demand for coffee that could be stored for a long time and enjoyed easily at any time.
