has anyone heard of utada doing some type of charity with her music?

i'm doing this hero's project in English and i decided i want to base it on a JPop singer

it's not someone who has to be known as a hero, but someone who has heroic characterists

i heard of her final distance song being deticated to a friend of her's who was murdered, but i think that is not enough

can someone help me?
i would really appreciated it
