Umizaru

is a Japanese manga series written and illustrated by Shūhō Satō. It was serialized by Shogakukan in Weekly Young Sunday from 1998 to 2001. Yōichi Komori is credited with the original idea for the series, and he also did the research to make the series more authentic. The series focuses on Daisuke Senzaki, an officer in the Japan Coast Guard, and tells the stories of shipwreck rescues and other incidents where the coast guard plays a role. The plotlines in the series were drawn from incidents and accidents which actually happened while the manga was being written (similar to the "ripped from the headlines" tagline used by various Law & Order series). The manga has been adapted into two NHK high-definition specials, four films, and one drama series. Media
