Y2J (traditional Chinese: 神木與瞳; simplified Chinese: 神木与瞳; pinyin: Shén Mù Yǔ Tóng) is a Taiwanese rock band composed of two participants (Yuming Lai and Jane Huang) from the 2007 season of One Million Star, a singing competition. The band released its debut album "Live For You" on 25 August 2008.
The two-member band's English name is derived Yuming Lai's first initial (Y), the number of band members (2), and Jane Huang's first initial (J). The band's Chinese name "Shenmu yu Tong", means "sacred tree and pupil (of the eye)". "Shénmù" (神木), meaning "sacred tree", comes from a large tree in Lai's village which shares the name "Yuming". "Little Tong" (瞳 tóng, "pupil")" is a nickname Jane Huang has had from childhood.
