ID maker mark

[WimA]

Dear all,
first post here after reading quite bit. I was hoping to get your help on identifying a pot from the marking. One marking is '77', the other, I presume, is Chinese/Japanese/(maybe even Korean?). Any help would be appreciated.

It may be more helpful to post the whole pot too!

It's a mass-produced Japanese maker called Koyama just google 古山鉢

Thank so much for the help. The knowledge gathered here is amazing! Here is a picture of the pot.
