I figured that I've mentioned this program enough times on some of the other articles that it was time to give it its due. "NHK Kayo Concert" is just one in a long line of prime time programs on Japan's main government network focusing on showcasing veteran kayo kyoku singers and their big hits. The current program got its name change in 1993 and has continued thusly for the past 20 years. And in North America, TV Japan has been showing on the same night, although it broadcasts here at 9 p.m. instead of the 8 p.m. start in Japan.
Although we also get "Music Station" here on Sunday nights, I've been more faithful to the kayo kyoku show since I get to hear a lot of the songs of my childhood and youth. So, I get to see veterans like Saburo Kitajima, Sachiko Kobayashi and The Cool Five. However, there are also younger folks such as the Prince of Enka, Kiyoshi Hikawa（氷川きよし）, who also make regular appearances.
Since it takes place at NHK Hall in Shibuya, Tokyo, the same venue where the Kohaku Utagassen takes place annually, I usually think of "Kayo Concert" as being the weekly shortened version of the 2nd half of the Kohaku (when most of the enka performers used to appear). The singers still come out wearing their Tuesday best, whether it be suits, gowns or kimono. And the themes change from week to week. One week may be a tribute to Hibari Misora, the next week may go for seasonal songs.
Perhaps I'm getting old-fogeyish, but I get quite a lot of enjoyment watching this bit of old-style Japanese elegance and entertainment. And perhaps if the series continues under its current title or a new one in another decade, Seiko Matsuda or even Dreams Come True may come aboard. :)
