Obscure is defined as
>not discovered or known about; uncertain.I'll go out on a limb and say the vast majority of people in first world countries know japanese is a language that exists, and maybe have heard it be spoken.
Obscure languages would be languages not known by many people at all, not just based on how many speak it.
