Otariiman

An interesting recent phenomenon is the otaku salaryman, sometimes called otariiman (オタリーマン^?). The 2000s has seen the rise of this type of salaryman, who appears perfectly ordinary at work, but is actually an intense otaku in his private life. It is currently not uncommon for salarymen to have a wide range of hobbies, but the “otaku as salaryman” is still treated as a relatively new entity in Japanese culture.

Otaku (おたく / オタク^?) is a Japanese term used to refer to people with an obsessive interests, particularly (but not limited to) anime, manga or Japanese video games.
