"Troublemaker" is a song recorded by Japanese boy band Arashi. It was released on March 3, 2010 by their record label J Storm. "Troublemaker" was used as the theme song to the drama Tokujo Kabachi!! (特上カバチ!!^?, lit. Extraordinary Quibbling) starring Arashi member Sho Sakurai. It was released as a CD single in two formats: a regular edition containing with two B-sides and the instrumental of all the songs and a limited edition containing the B-side "Yurase, Ima o" (揺らせ、今を^?, "Shake It Now") and a DVD.

On January 5, 2010, it was announced that Arashi would provide the song "Yurase, Ima o" as the theme song for the 2010 Winter Olympics news coverage on NTV. This was the group's third theme song for the NTV Olympic coverage, the previous two being "Hero" in 2004, and "Kaze no Mukō e" in 2008. The next day on January 6, 2010, Sakurai announced that Arashi would provide the theme song "Troublemaker" for his then-upcoming comedy drama during the drama's press conference.

On February 12, 2010, Arashi performed "Troublemaker" and "Yurase, Ima o" on Music Station's 1000th Episode Special. However, because of his work as the special newscaster for the Olympics news coverage on NTV, Sakurai could not attend the live music show as he had to go to Vancouver for the opening ceremony. Having finished his work with the Olympics, Sakurai performed "Troublemaker" with the other members of Arashi when they once again went on Music Station on March 5, 2010.
