Honto is a Japanese (e)books store. On Mac there is an app with which you can read purchased books. These are stored not as epub files but as folders under: ~/Library/Containers/jp.co.dnp.hontoformac/Data/Library/Application Support/Contents/

The contents of these folders is similar to epubs:

ls -l ./^011279304/ -rw-r--r--@ 1 user staff 32 Aug 6 20:18 DN000.bin drwxr-xr-x@ 8 user staff 256 Aug 6 22:39 contents drwxr-xr-x@ 397 user staff 12704 Aug 6 22:37 temp

ls -l contents total 328 drwxr-xr-x@ 6 user staff 192 Aug 6 22:37 META-INF -rw-r--r--@ 1 user staff 2496 Aug 6 22:37 book.bin -rw-r--r--@ 1 user staff 158222 Aug 6 22:37 dssdlTotalProgress.plist drwxr-xr-x@ 7 user staff 224 Aug 6 22:39 item -rw-r--r--@ 1 user staff 20 Aug 6 22:37 mimetype

cat mimetype application/epub+zip%

Obviously the content of these files is encrypted. Is there any chance to remove the DRM?

Not any tool I'm aware of currently.

Please update if you find anything.

I found windows location for the .epub files, it seems they're split between a two folders containing .jpg and .xhtml, respectively.

C:\Users\user\AppData\Local\DNP\honto\Contents\@^011572561\B-27461-123885646-001-001_DIVF4\epub\item

it seems the honto windows app launches a program, called ImageViewer, when opening a ebook through the app. that seems like the reason why the .jpg in the book's folder can't be opened with the normal software.

You can use this software to convert downloaded books to epub. https://jp.epubor.com/honto-converter/ Download your book using Honto windows client and it should show up on epubor. I used this as reference https://www.youtube.com/watch?v=OSkYhLZbiuM&pp=ygUZRXB1Ym9yIEhvbnRvIENvbnZlcnRlcu-8iA%3D%3D
