I don't understand the debate, it was a clearly used weapon of samurai cavalry forces. (It was in the old game too.)
No, it was not clearly used. We have some evidence in the form of a few illustrations (not many), but that's it. There aren't any actual records of their mounted use, as far as I'm aware.
