vintage Japan blue & white porcelain rice or noodle bowls, ginkgo & flower

Unmarked (made in Japan) vintage blue and white china rice bowls, both in excellent condition. These are 6" in diameter across the rims, and stand about 2 3/4" tall.

Each is a different design (one a ginkgo, and one a plum blossom branch, I think?). I don't know if these are traditional designs or just pretty nature inspired patterns in a 20th century chinoiserie style, but they're beautiful and very detailed.
