Again, I'm not as much of an enka fan as I am of the other genres in kayo kyoku, but sometimes after listening to a lot of New Music, City Pop or just plain J-Pop, I often go to enka as a bit of a palate-cleanser. Get down to the basics, so to speak. This is one song that helps. I used to listen to it as a kid, and I always remembered the saxophone intro and the drum roll leading to Takashi Hosokawa's （細川たかし）cue.
Hosokawa was born and raised in Hokkaido, and had been working as a singer in Sapporo's entertainment district of Susukino, when he was discovered by a Tokyo production company and invited to come down to Tokyo. He did so, promising his family that if he didn't succeed within a year, he would return home.
"Kokoro Nokori " (Regret) was Hosokawa's debut, and it turned out to be a huge success. Written by Rei Nakanishi（なかにし礼） and composed by Taiji Nakamura（中村泰士）, Hosokawa sings about being such an idiot for loving someone from afar despite all the gossip behind his back and finally deciding to leave town. In fact, the original title of the song was to have been "Watashi wa Baka yo ne"(私はバカよね.....I'm A Fool, Aren't I?), but considering that this song was to have heralded a major debut, wiser heads prevailed. However, it was noted that the first line which contained the "fool" reference left quite an impression.
The song, released in April 1975, hit No.1 on the Oricon charts and stayed there from July 28 to August 18. 800,000 copies were sold. It, and Hiromi Iwasaki's（岩崎宏美） "Romance" were in a tight battle for the Japan Record Awards' Newcomer Prize with Hosokawa coming out on top.
Of course, Hosokawa got onto that year's Kohaku Utagassen, as "Kokoro Nokori" ended up as the 8th-ranked song of 1975.
