In 2005, he changed his last name from Moriuchi (森内) to Morita (森田) due to the divorce of his parents. However, in the June 2012 issue of the magazine, Rockin'On Japan, he stated in an interview that his real name is Takahiro Moriuchi.[5] In 2013, he is shown again in a photo using his last name, Moriuchi, where all ONE OK ROCK band members held a written sign of their real names. The photo was taken by photographer, Rui Hashimoto.[6]
