Kuchiki no Tō (朽木の灯, literally "Light of the Decaying Tree"[a]) is the fourth studio album by Japanese rock band Mucc, released on September 1, 2004, by Danger Crue Records.

Guitarist and principal songwriter Miya said that prior to Zekū (2003) and Kuchiki no Tō (2004), his lyrics were about past events and "traumas" he experienced, but with these two albums he wrote about present inner feelings within the band.

[2] Despite audiences loving the shows, he seems to regret having done this as he speculated that he drank a lot on those tours so he would not have to face what he was expressing on stage, and stated that there is one song on Kuchiki no Tō that he will no longer play.

The songs "Namonaki Yume" and "Monokuro no Keshiki" were re-recorded by the band for their 2017 self-cover album Koroshi no Shirabe II: This is Not Greatest Hits.

An unapologetically bleak tour-de-force of melancholia, Kuchiki no Tō tapped into an inner darkness, hellbent on implosion, and channelled it through Tatsurou's tragically ravishing shrieks."
