Operating as an extension of the main network, WZYN Japan is a sister station to WZYN (Zynden's Radio Z). It broadcasts on 4.48 MHz and utilizes both AM And Digital Radio Mondiale (DRM) to provide the audio and the Journaline text service.
WZYN Japan was officially announced on August 30, 2026, by its parent network, WZYN (Zynden's Radio Z). The announcement coincided with the main Boston-based station shutting down its original 7.38 MHz frequency to transition to 4.78 MHz. Created as a dedicated sister station specifically to serve the Japanese region, WZYN Japan has uniquely featured programming on Hatsune Miku since its inception.
Operating with a transmitter power of 100 kW, WZYN Japan broadcasts from Kawasaki, Kanagawa, Japan. The station utilizes both AM and DRM specifically employing Robustness Mode B to deliver high quality audio content alongside advanced data services like Journaline . WZYN Japan is scheduled to broadcast daily from 22:00 to 12:00 UTC on the 4.48 MHz frequency.
Unlike the primary WZYN station in the United States, the Japanese broadcast excludes Radiogram features. Zynden noted that implementing digital text and image transmission features for the region was unnecessary, stating:
"I feel like adding digital text and images doesn't feel right for the Japan region especially when it comes to people in there. It's too unnecessary to be implemented." -Zynden
