This is a Japanese Satsuma plate. You had sent in images of a Satsuma vase as well and I included some information about Satsuma ware in that appraisal. I will also add a link to more information about this style below. A Satsuma plate like yours was probably made in the late 19th to early 20th century and has a Fair Market Value between $20 and $60.
