Not a website but a tool: https://openaudible.org/ works really well for Audible audiobooks, and it's the only tool I found that works for Japanese Audible.
Note that you have to pay for an OpenAudible license to be able to use it with more than a few tracks.
If you can get your activation bytes from one of your DRM-protected files using https://audible-converter.ml, you can then just use
ffmpeg
(e.g.ffmpeg -activation_bytes XXXXXXXX -i audiobook.aax -c copy audiobook.m4b
) or https://github.com/audiamus/AaxAudioConverter to remove the DRM.Unfortunately this doesn't work for the Japanese store (and a few others) that seem to use a different DRM scheme with a separate key for each file, so you have to use OpenAudible for these.
