Morinaga Chorus

There is a product renewal article on Nikkei Trendy. Not overly interesting, just a new flavor - peach - but it mentions in the article that the Morinaga Chorus product was first introduced in 1927, which was a surprise. That took the history of lactic acid drinks back earlier than I had been thinking. Sure enough, a quick search shows that Calpis was introduced in 1919.
