In September 1922, Oguri began working at a printer.

According to researcher Sari Kawana, he was one of the authors involved in writing "mad scientist murders," a subgenre within the larger stream of Japanese detective fiction during the 1920s and 1930s. He used the motif of the "mad scientist" and his uncompromising attitude toward his work to criticize the widespread overconfidence in the possibilities of science and to highlight the potential incompatibility between science and ethics. Other writers involved in that genre were Kozakai Fuboku, Yumeno Kyusaku, and Unno Juza.
