Vintage Hand-Painted Delicate Porcelain Tea orders Service Made in Japan

These cups are so delicate I can't believe they've survived in the shape they have. I know that people have strong feelings on which china is valuable and which is not, but I'm just a simple gal who loves a hand-painted piece with lots of character.

Teapot measures 10-1/4" in height x 7" in length (including handle) and 5" the other way. In lovely condition - no chips I can see
Cups measures 3-1/4" in height x 3-1/2" in length (including handle) and 2-3/4" the other orders way. There are some paint slip ups but no chips that I can see. One cup has a dark mark on the bottom.
Saucer measures 5" across x 1" in height

The whole is in very good condition, except for a small shine on one of the saucers (see photos) and a chip on the back of one plate.
