The Birthday is a Japanese rock band formed in 2006, shortly after ROSSO’s disbandment. Having played together in both ROSSO and Midnight Bankrobbers, チバユウスケ (Chiba Yusuke) and イマイアキノブ (Imai Akinobu) decided to form a new band together, and were quickly joined by クハラカズユキ (Kuhara Kazuyuki) on drums and ヒライハルキ (Hirai Haruki) on bass. It’s worth noting that drummer Kuhara Kazuyuki used to play with Chiba Yusuke in the well-known garage rock band THEE MICHELLE GUN ELEPHANT
