This is Chiaki's most representative song in her long career which began in 1969. She was comfortable in both enka and pop, although "Kassai"would be considered a kayo kyoku pop song. It was a hit right from its release, having started from No. 7 on the charts and then reaching its peak of No. 2 the following week. It also earned a Japan Record Award along with sales of 3 million records.
Chiaki also became a TV personality and appeared in commercials. In 1992, though, with the death of her actor husband, she completely retired from show business.
