What makes Kusabi by KAT-TUN notable?

'Kusabi' debuted at number one on the Oricon Albums Chart, affirming KAT-TUN's continued popularity in the J-pop industry. The album was well-received for its production quality and diverse musical styles, drawing particular attention for its lead single '楔-kusabi-', which became a staple in their live performances. Its commercial success helped solidify the band's relevance during a time of intense competition among contemporary J-pop acts. Released on November 27, 2013, 'Kusabi' marked KAT-TUN's return to the music scene after a brief hiatus following their previous album, 'Chain'. This sixth studio album was pivotal as it underscored their evolution into a more mature sound while retaining their signature pop essence. At this point in their career, KAT-TUN had already established themselves as a leading boy band in Japan, yet they were navigating changes in their lineup and artistic direction.
