Antique Japanese Hand Painted Porcelain Plates

These were bought by my grandparents when they lived in Japan in the late 40's/early 50's.  There's at least a dozen of them.  Beautiful hand painted designs with gold paint and what appears to be gold leaf on the outer rim.

Photos are one example, others are similar designs but being hand painted they are different. 

Thanks for looking, any info is appreciated!
