It's been announced that Sakanaction's Yamaguchi Ichiro (Vo, G) will be taking a break from his activities due to his poor health. 

According to the announcement, Yamaguchi had been feeling washed out and fatigued since May. However, the band members, staff, and his counselor respected his wishes to continue his activities until now. Then last month, Yamaguchi received diagnosis from his doctor that he requires rest. As such, it was decided that he temporarily suspend his activities.

Due to this, Sakanaction and Underworld's concerts on July 6 and 7 at Tokyo Garden Theater, as well as the Aichi, Tokyo, and Ishikawa concerts of the band's nationwide hall tour 'SAKANAQUARIUM Adult NAKED' have been postponed. The hall tour was scheduled to kick off on June 14, but due to various circumstances, it hasn't officially started yet.
