The '70s were a booming period for whisky in Japan. The decline that was about to hit in the mid '80s and run well into the 2000s was still a while off and the two giants Suntory and Nikka were trading blows for market share.
Suntory, in particular, were always quite innovative in their approaches to product releases and the marketing around them. Often that included Western celebrities who could pick up a big paycheck in a foreign country without it impacting too much back home. YouTube wasn't a worry back then.
It may not have been the coolest at the time, but this minute-long TV ad from Sammy Davis Jr for Suntory in 1974 certainly proves that while flavours may change, class is forever.
