Tomokawa Kazuki (友川かずき / 友川カズキ) is an Akita-born singer-songwriter & painter with a considerable cult following. While he remains largely unknown to the public, I think he is one of the greatest musicians northeastern Tohoku-region has ever produced. This song is "Ikiterutte Ittemiro" (生きてるって言ってみろ, trans. Say You're Alive).
Next one is "Waltz".
