Hiroomi Tosaka

Hiroomi Tosaka was born on March 12, 1987, in Tokyo, Japan. He did not have too much enthusiasm about studying as a high school student, so he decided to go to a technical college for hairstylists after high school without too much consideration about his future. He went to Kubota Barber Beauty College, and after graduation, he worked at a hair salon. He quit his job after 6 months and started to work as a shop assistant at an apparel store in Daikanyamachō, Shibuya. The customers he served during that times included Takahiro and Ryohei Suzuki.

Though he was always fond of singing, he considered being a singer a dream too unrealistic to achieve, and therefore preferred a future as a hairstylist. When he was studying at Kubota Barber Beauty College, Takahiro passed the Vocal Battle Audition 2006: Asian Dream and became a vocalist of Exile. Tosaka was very much impressed and inspired by this since Takahiro had also been a hairstylist before the audition. For this reason, the dream of becoming a singer became serious for him. In February 2010, Tosaka participated in Exile presents Vocal Battle Audition 2: ~Yume o Motta Wakamono-tachi e~. He received a flyer and decided to have a try, but he did not have any experience at singing besides being good at Karaoke. Since he had not received professional vocal training or sung in public before, he was called the "Cinderella Boy without Experience" during the audition. However, his talent began to show and helped him to pass the audition. He then met Ryuji Imaichi in the second round of the audition, and they both considered each other to be strong competitors after seeing their performances for the first round on Shûkan Exile's coverage of the audition. As Imaichi and Tosaka both were selected as two of the ten finalists after the third round, it was announced that the two winners of Vocal Battle Audition 2 would become the vocalists of the new dance and vocal group Sandaime J Soul Brothers.
