Kabu no Isaki (Japanese: カブのイサキ; lit. 'Isaki of the Cub') is a Japanese manga series written and illustrated by Hitoshi Ashinano. It was serialized in Kodansha's seinen manga magazine Monthly Afternoon from June 2007 to November 2012. Kabu no Isaki shares many characteristic hallmarks of Ashinano's style: fascination with aeronautical themes; a setting in the future; a setting on and around the Miura peninsula; a vision of Japan that is isolated and nostalgic; and a natural world full of mystery that the protagonists explore with a sense of wonder.
