I am a cartoonist and illustrator based in Tokyo.

I create comics and also do illustration work, from posters to character design for a variety of clients including L’Oreal China, Slate, The Apatow Company, Tezuka Pro, Marvel Comics, Image Comics, Kodansha, NHK Broadcasting Station and DC Entertainment.

I co-created with Joe Kelly the I Kill Giants graphic novel, which has been adapted as a movie directed by Anders Walter. Other comic titles include Henshin, Never open it and the ongoing series Umami.
