To the back left and central you'll see the colour purple feature on the huts. The backdrop is a mountainous setting, and the foreground showing a calm water. There are numerous trees & shrubs, as well as a wooden structure in the foreground as well as other towers & huts dotted across the scene. The high quality wear is evidenced by the minute crackle glaze observed on the plate, as well as the fact that the porcelain doesn't ring like china ware. The word Kyokuzan translates roughly to "Morning Sun Mountain", and could be the name of the place as depicted in the image on the cup & saucer.
Markings on the back confirm this is for Shimazu and Kyokuzan. 2x Markings are also seen in the wooden structure in the central image, Dai (meaning great) and 2x other symbols. Both cup & saucer are in excellent condition with only slight paint fade in places. If you have any further questions please ask.
