Birthday: April 27, 1980

One of editors of the Weekly Shōnen Jump. He is a thin, odd-looking man with a wide-eyed gaze and distinctive lips.

Hattori Akira was Akito Takagi's and Moritaka Mashiro's editor. He helped them with their names and eventually got them serialized for Detective Trap. Once they got serialized, however, Hattori had to hand them over to Miura due to conflicting responsibilities.

Hattori is often portrayed as one of the calmer and more calculated editors in the series. He comes across as a very wise and experienced editor which leaves him raising his voice only when he sees it absolutely necessary to do so. He is very fond of Takagi and Mashiro and continues to be interested in their progression as mangakas, offering off-hand advice to Miura when he can.

Hattori is editing One Piece.

Hattori's face (especially his lips and eyes) resemble the character Ryuk from the manga Death Note which is drawn by Takeshi Obata.
