Audio Media Turns into Intellectual Asset: A Milestone Book Release

In a groundbreaking moment for audio media, the podcast "Professor Maru's Tsuminhanashi—Criminology for Citizens" is set to be published as a book on August 6, 2026, by Genda Jimbunsha. This initiative comes from OtoBank, a company based in Bunkyo-ku, Tokyo, led by CEO Yuya Kubota, and marks the first time a podcast produced by the company has been transformed into a book. This development demonstrates the potential of audio content to cultivate passionate fan communities and evolve into valuable intellectual property (IP).

A Journey From Podcast to Print

"Professor Maru's Tsuminhanashi" emphasizes discussions on criminology in a way that makes the subject approachable. Hosted by Professor Yasuhiro Maruyama, a leading expert in criminology at Rissho University, along with Fumi Minamiguchi and freelance paralegal Yuki Yamaguchi, the podcast aims to shed light on crime, delinquency, and criminal justice sectors that are often shunned. The show's inception was driven by Maruyama's desire to raise awareness about the societal implications of criminal behavior.

The podcast has captivated audiences since its inception three years ago. The engaging and relatable Kansai dialect of Professor Maruyama, coupled with insightful dialogues with his guests, makes the heavy topic of crime engaging and educational. By blending in real-world experiences, such as fieldwork in prisons and discussions on related films, the show has released a total of 65 episodes, garnering tremendous support through crowdfunding and community engagement.

Endorsements and Celebrations

The book will include a recommendation from renowned Akutagawa Prize laureate, Kikuko Tsumura, who emphasizes the pervasive nature of crime and the importance of understanding its roots. The celebration for this book release will include two special events: a talk and signing session with Professor Maruyama on August 8 in Tokyo and August 17 in Osaka.

Transforming Audio Content into Valuable Assets

OtoBank's Executive Officer in charge of the podcast business, Masaaki Toyama, reflects on the significance of this achievement, emphasizing the value of audio content in community building and fostering passionate listeners. The integration of engaging audio content and community formation has turned this project into a successful IP that serves as an inspiring example for businesses considering fostering their own media. Toyama notes that their approach was not just technical support but also included creative planning to maximize outreach and community growth.
