|Past members||Jin Akanishi|
KAT-TUN (カトゥーン Katūn ) is a Japanese boy band formed by Johnny & Associates (Johnny's) in 2001. The group's name is an acronym based on the first letter of each member's family name until the departure of Jin Akanishi in 2010. As of 2010, KAT-TUN stands for Kazuya KAmenashi, Junnosuke Taguchi, Koki Tanaka, Tatsuya Ueda, and Yuichi Nakamaru. Their debut on March 22, 2006 was marked by a tripartite release of a CD single, album and music DVD on their exclusive record label J-One Records. Since then, all of their single, album and music DVD releases have debuted at number one on the Oricon music and DVD charts.
2001–2005: Formation and pre-debut activities 
Before becoming KAT-TUN, each member belonged to different trainee units within Johnny & Associates. In 2001, eight members were chosen to become a temporary dancing unit in order to support Koichi Domoto in the NHK music program, Pop Jam. The eight members were switched around before it officially became KAT-TUN, with the current five members plus Jin Akanishi. Although the formation was only meant to be a temporary support unit, KAT-TUN gained a great deal of attention and became a solid unit.
In 2002, in response to many requests, KAT-TUN held their first concert called Okyakusama wa Kamisama - Concert 55man Nin Ai no Request ni Kotaete!! (お客様は神サマーConcert 55万人愛のリクエストに応えて!!), for which 550,000 people tried to get tickets. That same year, they performed eleven shows in a single day. This is the current record in Japan for the most performances in one day. Since then, KAT-TUN has held concerts in Japan almost every season.
In 2003-2004, their popularity rose to that of a debuted group, to the point where they performed on Music Station multiple times before debuting. In 2005, KAT-TUN released their first major DVD, KAT-TUN Live Kaizokuban (KAT-TUN Live海賊帆 lit. KAT-TUN Live: Pirate Sails ), which topped the Oricon yearly chart for the best-selling DVD.

Within the first week, Best of KAT-TUN, "Real Face" and Real Face Film topped all three Oricon weekly charts by selling 556,548 copies, 754,234 copies and 374,202 copies respectively. They became the second artists to do so, the first being Ayumi Hamasaki. With these numbers, KAT-TUN holds the record for the highest weekly single debut sales (previously held by Arashi with their debut single "Arashi" of 557,000 copies sold in 1999). In addition, "Real Face" topped the Oricon charts for three weeks straight, becoming the first debut single to do so in Japan in 8 years 8 months since KinKi Kids' debut single "Garasu no Shōnen." The single sold over a million copies in nine weeks, making "Real Face" the highest selling single for the year 2006.
In March 2006, KAT-TUN became the first group to hold their own performances in Japan's most popular stadium, Tokyo Dome, before debuting. They performed to 110,000 people over two days and about 630,000 people in total during the tour. About three months after releasing "Real Face", KAT-TUN released their second single, "Signal", on July 19. It topped the Oricon weekly chart by exceeding 400,000 in sales.
