Lead (/liːd/) is a Japanese hip-hop dance and vocal group, initially formed under the name Rhymix in Osaka, Japan in March 2002. They went through two name changes before debuting as "Lead" in May 2002 under the Pony Canyon sub-label Flight Master. The group consists of Shinya Taniuichi, Keita Furuya, Akira Kagimoto and, formerly, Hiroki Nakadoi.
Upon debuting on July 31, 2002 with "Manatsu no Magic", the group experienced early success due to their dancing and vocal skills at a young age. The release of their second single "Show Me the Way" earned the group the Best Newcomer Award during the 44th Japan Record Awards. Their debut album Life On Da Beat took the No. 5 spot on the Oricon charts.
In 2010, the group moved from Flight Master to the parent label of Pony Canyon with their single "Speed Star."
Beginning with the single "Wanna Be With You" (2012), the group began a string of top-charting singles. The single peaked at No. 3 on Orion and their singles have continued to chart in the top five. Their album The Showcase (2016) became their highest-charting album at No. 2 and their following album Milestone (2018) became their longest-charting album, remaining on the charts for seven weeks.
In 2013, leader and lead vocalist Hiroki Nakadoi left the group after feelings of inadequacy. The last single he was featured in was "Still", and he officially left the group after their 2012 Upturn tour.
