Asahi Sonorama
Asahi Sonorama was created as a division of Asahi Shimbunsha on September 9, 1959, under the name "Asahi Sonopress". It was initially established to record interviews, news, crime scene investigations, and articles on a variety of topics, and then release them on tape and sonosheets in the audio recording magazine "Asahi Sonorama" (from whence the company got its name). While doing this, the company also began publishing other magazines, manga collections, and novels.
