@coolboymew @SuperDicq @Hyperhidrosis Unauthorized copying of 漫画 in 日本 is relatively uncommon as there is decent service - those come in books of good resolution, that don't have proprietary software.

New volumes aren't too expensive and even if you are broke, you can pick up 2nd hand volumes for a cheap price (generally B-grade quality I reckon (someone breathed on it)).

I would expect unauthorized copying of アニメ to be far more common, as pretty much all studios won't sell you a decent copy without proprietary software (you can get DVDs, but 480p is really lousy).

The only decent quality encoding that is available seems to be blurays and well blurays are designed to not play without proprietary software (free software bluray playback is now possible provided you have the disk encryption key - which can be a problem for the latest blurays, where the key is only stored on a remote server that the player fetches over the internet)).
