Rules for using Ondoku
Ondoku can be used at educational institutions such as public schools and school corporations with exemptions from certain prohibited items.
Using for school broadcasts for free: You can use Ondoku audio for free by providing credit attribution.

For use outside of educational institutions, please use it according to the normal commercial use rules.
How do you actually provide credit attribution?
When using it for free, please do the following three things:
- Post a notice in front of the broadcasting room or staff room stating that Ondoku is being used for announcements.
(Create a poster. Introduce it by including the Ondoku URL or QR code, etc.) - Display information on the SD cards containing the audio or near the broadcasting equipment.
- Ensure that faculty, staff, and students are informed about the audio source being used.
For paid plans (from 980 yen/month), these three steps are unnecessary. You can use the audio as is.
