Antique Japanese imari 12x9.75

Antique Japanese imari 12x9.75" porcelain platter w scalloped rim Chinese export. COULD BE Chinese but more likely Japanese ? Thick porcelain almost like restaursntware. Awesome all original condition. Looks 1880s to me ? Someone else could better identify this piece.... very pretty ! From a local estate. 27 years experience and super SAFE shipper ! One tiny pin prick sized nick on rim, in the middle of the last photo..... almost invisible. No hairlines ......
