Hi again, the mark reads " Dai Nippon Kutani Sekizan Sei" which means " Great Japan, Kutani, Sekisan made it". The "Dai Nippon" marking is typical for the Meiji period. About the maker I could not find any information, but there are many good makers about which we know nothing...
frogpatch and mart, you are right, asian items are very confusing, I just try to help whenever I know at least something!
