ライジング・サン・ロックフェスティバル
As 2008 marked the 10th anniversary of Sheena's professional debut, she resumed solo activities as "Ringo Sheena" for the first time since the formation of Tokyo Jihen. She participated in the summer Rising Sun Rock Festival both as a soloist and as a member of Tokyo Jihen. The activity of Tokyo Jihen was thus restricted during this period.
