I'm having some trouble finding out how many case marker particles (格助詞) there
are in Japanese. The answers I find range from 9 to 11, depending on the site.
Almost all of the ones I've found agree on the following:

> が、で、に、を、へ、と、より、から、まで

The 2 that seem to be contested are の and や. I understand a particle belonging
to several classes, but I don't know why some sites leave those 2 out
entirely. Is this simply something that Japanese speakers and scholars
disagree on?

question
particles
How many case marking particles are there?
One of the difficulties in answering your question is that there isn't really
any clear consensus on how to categorize case particles in Japanese. It's
problematic because the standard conceptual grouping of [grammatical
case](https://en.wikipedia.org/wiki/Grammatical_case) can lead to vague
definitions which aren't quite satisfactory. For example, Tsujimura (1996)
lists only five pure case particles: が (Nominative), を (Accusative), に
(Dative), の (Genetive), and includes the topic marker は as a case marker.
Obviously the inclusion of は doesn't conform to case markers in Indo-European
languages.

You could argue that other Japanese particles like で are case particles
('Instrumental Case), but Tsujimura disputes that, claiming that case
particles don't contain "specific semantic content" whereas で does have that
content. The difference is highlighted by the argument that you couldn't
acceptably omit で in casual speech, while case particles can be omitted.
Tsujimura also disputes まで ('Terminative Case') on the grounds that it can
immediately be followed by a nominative case particle, meaning that is should
be categorized as a postpositional particle rather than a case particle. Are
other particles like より truly Ablative case? If so, how does it differ from
から? The definitions are unclear.

As you see, there is no simple categorization which everyone agrees on because
it all depends on how to define it, and there seem to be differences in how
scholars define it as applied to Japanese. I think we have to just wait for
the scholars to argue it out among themselves before we can say definitively
what the number is.
