In Japan, "Koi ni Ochite"(Fall in Love) did even better. Released in August 1985, it took 7 weeks for it to hit No. 1 on the Oricon charts, and not only did it become the 3rd-ranking single of the year but it also became the 6th-ranking single for the next year. It was originally a theme song for a drama sequel titled "Kin'youbi no Tsumatachi e 3"（金曜日の妻たちへ ３....To the Wives of Friday 3), but more importantly, it was the debut single and launch pad for Kobayashi's career as a professional singer. Kobayashi composed the song while the prolific Reiko Yukawa（湯川 れい子）provided the lyrics.
Kobayashi was born in Tokyo in 1958 where she earned a degree in philosophy at the prestigious Gakushuin University. She then became a secretary for a professor before working in a similar position for a music publishing company. Her very first work in music was as a composer of a song for the folk duo, Bread & Butter in 1984. Then came "Koi ni Ochite".
The aspect that struck pretty much everyone around her and everyone (including me) who has listened to her is how much she sounds like the late Karen Carpenter. Now, her voice is actually a little higher in register when compared to Karen, but the cadence is there and the songs that she sings are basically in the same genre as that of The Carpenters. Eventually, Kobayashi and Richard Carpenter were introduced to each other, and the result was her 4th album, "City of Angels" which he produced and provided backing vocals. The Carpenters are considered even bigger legends in Japan than in their native United States, so that couldn't have hurt Kobayashi's career.
