Oriental Bowls, Handpainted, Japan

These handpainted colbalt blue rim bowls have red, green, pink and blue. There are 4 ladies in each with mountain in the background along with lake and houses. They are 5 1/2" across. There is some minor wear on the edge where there is gold in the dark blue. No chips, cracks or crazing. There is no backstamp. I believe they are from Japan.
