Oriental Tea-set.

I was wondering if anyone could shed any light on this tea-set that i have. There is 12 tea cups and saucers a tea pot and 2 smaller pots. There seems to be no stamp on the bottom of anything. The china is very thin and each piece seems individualy hand painted. All i know is that it was purchased shortly before the second world war from an antiques shop in china/japan apparently. Apologies for the not so great pictures and the general vagueness of all this.
