北見沢惇 — 1960
First released in June 1960 by Jun Kitamizawa on Nippon Columbia. The single went unnoticed and the song was shelved until Koga found a singer worthy of it.
Released as a single on June 10, 1966, it became a million-seller for Hibari Misora. The spoken interlude she requested was added in March 1967 and has been the standard version ever since.
