Tenrikyo Doyusha has made four audio books available for streaming on its Tenri Jiho Online website. These are for four pre-selected books in Japanese, and the audio recording is an AI-generated voice. Free streaming is available for those who register with Tenri Jiho Online (free registration).

Moreover, a paid subscription to their "standard membership" (360 yen a month or 3600 yen annually) provides access to two more books (six total). “Premium membership" (600 yen a month or 6000 yen annually) allows for eighteen more books (twenty-four total). 

These memberships also include access to digital versions (not audio) of a wide array of Tenrikyo books in Japanese.

While the audio is in Japanese, if you know anyone around you who could make use of such resource, please let them know.
