As of 2014, he has gone freelance. His most recent serializations were Studio Pulp for Rakuen Le Paradis of Hakusensha and Kakushigoto in Monthly Shōnen Magazine, both of which concluded their run in 2020.

Sayonara, Zetsubou-Sensei was his first work to be adapted into an anime and was awarded the 31st Kodansha Manga Award in the shōnen category.
