Asian Tea Pot and Tea Cup

Hello-
I am hoping someone can help me Identifying this teapot and cup.I think it's absolutely lovely and so colorful! I had 4 tea cups, but I broke two of them. (in the thrift store!) I was so sick when I dropped the cups!(not to mention embarrassed!)
ANY help on these would be great! Japanese? I think they are handpainted. The cups are thin so maybe bone china? Possible age?
I know ZERO about China. This is the first time I have ever bought or dealt with China. The price was right and they were so lovely that I couldn't pass them up. Then I broke two of them and was reminded on why I usually stay away from China Ilse! Anyway- any help is very much appreciated in Identifying and aging these fragile little babies.
THANKS
