This album set a milestone by becoming the first Japanese record label to sell over one million LPs.
The third album released in 1973. It contains 13 songs in total, including the pre-release single "Kokoro Moyo," which was his first to enter the top 10 of the Oricon singles chart, and the title song "Koori no Sekai."
This was a London recording, which was rare for a Japanese artist at the time. The third track, "Kaerenai Futari" (We Can't Go Home), was co-written with Kiyoshiro Imawano. Incidentally, the guitar Yosui is playing in the cover photo is Kiyoshiro Imawano's. The unique white look of the cover photo is perfect for the image of this album, but it was apparently the result of leaving the negatives in the developer for too long.
