Mamoru Samuragochi, a deaf composer who has been dubbed “Japan’s Beethoven”, has admitted hiring someone else to write his music for nearly two decades.

Mamoru Samuragochi, 50, shot to fame in the mid-1990s and is most famous for his Hiroshima Symphony No 1, dedicated to those killed in the 1945 atomic blast.

He has now confessed he has not composed his own music since 1996.

The real composer of the musician’s “hits” has not been formally named.

According to his now defunct website, Mamoru Samuragochi was taught how to play the piano by his mother when he was four and began playing Beethoven and Bach when he was 10.

Mamoru Samuragochi made his first breakthrough creating music for video games including Resident Evil and Onimusha.

He completely lost his hearing when he was 35 but continued to compose music, apparently relying on his “absolute pitch”.

Mamoru Samuragochi’s Hiroshima Symphony No 1, completed in 2003, became a major classical music hit, selling more than 100,000 copies in Japan.

It went on to become an anthemic tribute known informally as the “Symphony of Hope”, after Mamoru Samuragochi was filmed meeting survivors in the tsunami-battered Tohoku region in 2011.

Apologizing on his behalf, Mamoru Samuragochi’s solicitor said the musician was “deeply sorry as he has betrayed fans and disappointed others”.

“He knows he could not possibly make any excuse for what he has done. He is mentally distressed and not in a condition to properly express his own thoughts.”

Japanese broadcaster NHK quoted Mamoru Samuragochi saying: “I started hiring the person to compose music for me around 1996, when I was asked to make movie music for the first time.

“I had to ask the person to help me for more than half the work because the ear condition got worse.”

It is believed Mamoru Samuragochi paid for the commissions while giving the ideas for his work to the other composer.

“I’ve been told that there are certain circumstances that make it hard for the person [who composed the works] to come out in public,” his lawyer said.

“Samuragochi has therefore come to describe himself as the sole composer.”

Although the identity of the “ghost” composer has not been formally identified, Japanese media has named him as music teacher Aragaki Takashi.

Japanese Winter Olympics hopeful, figure skater Daisuke Takahashi, has also been caught up in the scandal as his program includes a dance to Mamoru Samuragochi’s Sonatina for Violin – also not penned by the musician.

Nippon Columbia, Mamoru Samuragochi’s record company, said it was “flabbergasted and deeply infuriated” by his revelation.
