The folk group Kaguyahime [ja] released the song Kandagawa (神田川) on September 20, 1973, named after the Kanda River (Kandagawa).
With lyrics by Makoto Kitajō and music by Kōsetsu Minami, the single was a remix of a tune released the previous July on the album Kaguyahime Third.
The lyrics reminisce over the bittersweet experiences of living with a girlfriend in a small room during Kitajō's college days.
With sales of 1.6 million copies, it held the top spot on the Oricon charts for seven weeks (including six in a row) and was Kaguyahime's greatest hit.
[1] In 1974, Keiko Sekine (Takahashi) and Masao Kusakari starred in a film based on the song.
