I can only make out the small letters on the upper right hand corner. It says "Tokoname-yaki", which means that it was made near here in the city of Tokoname, one of several cities here in Japan famous for its pottery.
Good luck with the rest of it. It's most likely the potter's name or the name of the studio that made it or possibly even the tea bowl's name.
I thank you so much for trying... that's really important because I'm really looking for a Tokoname set because I understand them to be the very best available. Thank you too for trying to identify the other words!
Does 窶卮停?敕ｼ mean "Brown Beauty"?
