What is "ten-sei"

is the 33rd studio album by Japanese singer-songwriter Miyuki Nakajima, released in November 2005.

Like some previous albums 10 Wings, Hi -Wings- and Tsuki -Wings-, Tensei is composed of the songs Nakajima wrote for her experimental musical Yakai. All the materials appeared on the album were originally performed on Yakai Vol. 14: "24-Ji Chaku 0-Ji Hatsu" which was taken place at the Bunkamura Theatre Cocoon during January 2004. Except "The Mirage Hotel" which was already included on her 2003 Love Letter (Koibumi) album (Ten-Sei features newly arranged version of a song), most of the songs were appeared on the studio album for the first time.

From the album, "For Those Who Can't Go Home" was later released as a single (flip side was live recording version of "Relay of the Soul" which was taken from Yakai). It was featured as a theme song for the television drama Kemonomichi ( adaptation of the novel written by Seicho Matsumoto) starring Ryoko Yonekura and aired on TV Asahi in 2006. "Relay of the Soul" was also used in the drama series called On'na no Ichidaiki aired on Fuji TV during autumn 2005.
