RADWIMPS has unleashed the PV for their new song "Kaiko" through their official YouTube channel.

Soon after the Tohoku Earthquake three years ago, RADWIMPS launched a special website and released their song "Itoshiki". Since then, they've released their songs "Hakujitsu" on March 11, 2012 and "Buriki" on March 11, 2013.�

Regarding their new song, Noda Yojiro (Vo) said, "I don't know if this is suitable for this day, but it was born because of the happening three years ago."
