In 2001, a few high-school classmates formed the band Base Ball Bear. This pop-rock trio made their major debut with EMI in 2006. Their catchy tunes, with melancholic and thoughtful lyrics, are what made up their identity while they create new territories by collaborating with idols and hip-hop stars. The music had also caught the attention of overseas fans where their albums were released in Taiwan. To celebrate their 10th year anniversary, they held a solo concert at the Nippon Budokan in 2012. They continue to release new hit songs while touring the country.
