Ha. I do read Japanese, and speak it, and on rare occasion even write it by hand.
Why not choose an English release? Because it's a waste of both money and space. It's so much easier (and substantially cheaper) to just own NTSC-J and nothing else. Plus I could go on a rant about how localization is shit and there's censorship, and the occasional instance where the localizing studio has a God Complex and decides they know better than the original dev and alter the balance of elements in the game etc. etc. but I need not bother, certainly you've heard it all before, and already understand all these aspects. Even if none of these were issues there is the inescapable fact that translating ruins the emotional feel; Japanese has too many grammatical functions that do not exist in other languages and so the depth of a character and certain jokes; lots of things in speech is lost the moment you give up the original script. I value this content much like the authenticity of the audio and video by using a real console.
I don't need any of that noise. Real system (Saturn in this case), true audio and video, no censorship or altercations. The way it's meant to be played.
