You don't have to remove subtitle from MP4
Just rename SRT subtitle same name as movie
and VLC automatically play video with SRT file

anyway Yamb, My MP4Box GUI and MP4Muxer can mix mp4
or you can mix to MKV with MKVToolnix

1- I did that, and i got the two subtitles on each other (Japanese and English).

2- I did that too, but i usually gets two files after mixing, one is the movie file (without sound and the japanese subtitles still there) and the sound for the movie MP4 file!

I suspect that the MP4 file has "hard-coded" subtitles, and these cannot be removed...

... without screwing the picture quality as well. AFAIR, MP4s containing "soft subs" are somewhat uncommon ~~

~~ the format accepts only TTXT (officially) and IDX+SUB (unofficially).

If you disable subtitles in VLC player, when you play original file
and you have still displayed subtitles
so yes, subtitles its part of video, it's cannot be removed

Vlc disabled subtitles:

^ Maybe it was my usual "lack of good luck", but
the only time I tried MSU subtitle remover on a video with CJK subtitles (years ago), it didN'T work,
— I mean, it didn't remove anything : - /

The MSU subtitle remover does not work because it specifically try to match the shape of English characters (I guess).
A more universal remover requires the use of edge detection(for all shapes) and in-painting.
See my previous post for such examples.(The videohelp link is an example for removing Traditional Chinese characters; the one to my blog is a demo video for removing Japanese characters with thick and colored edge.)

Removing hardcoded subs? That's the dumbest thing I've heard all day.

if hardsubbed, then just download another release, without hardsubs, easiest and the best
