  "Kioku" (記憶, lit. "Memory", stylized as "La Mémoire") is a song recorded by Japanese singer Misia for her tenth studio album, Soul Quest. It was released as the album's lead single by Ariola Japan on May 25, 2011. "Kioku" is the theme song to the EX drama series Iryū Sōsa, starring Takaya Kamikawa.
  
  ## Background and release
  
  "Kioku" is Misia's first single in nearly a year and a half, since "Hoshi no Yō ni..." (2009). The single includes a duet between Misia and JP, titled "Kono Mama de Tonight", as well as a cover of the 1967 Frankie Valli song "Can't Take My Eyes Off You". The first pressing of the physical release features a remix of "Maware Maware" as bonus track.
  
  ## Composition
  
  "Kioku" was co-written by Misia and Gorō Matsui, composed by Korean composer and record producer BZ4U and produced by Shirō Sagisu. The song is composed in the key of B-flat major and set to a common time tempo of 65 beats per minute. Misia's vocals span from $F_3$ to $E♭_5$ in modal voice, and up to $G_5$ in head voice. TV Asashi producer Yumiko Miwa tasked Misia to write a song that would convey "hope and sympathy". Misia penned the lyrics to "Kioku" shortly following the 2011 Tōhoku earthquake and tsunami, and she describes thinking of recent events while writing the song.
  
  ## Critical reception
  
  CDJournal critics describe the song as a "majestic and beautiful" piano ballad with an orchestral arrangement. Misia received acclaim for the "presence" of her vocal performance, with critics noting "Kioku" as an example of Misia "showing herself at her best", and for writing lyrics with a strong message.
