1940s Bone China Lusterware Geometric Design 20 Piece Set for 5 Made in JAPAN For Sale

This appears to be a vintage Japanese lusterware porcelain tea set featuring a periwinkle-purple iridescent finish, hand-painted floral motifs, and moriage-style or fine line detailing.

Backstamps featuring the square rising sun motif with text like "Made in Japan" or related import marks were commonly used on export ceramics from the 1910s through the 1940s (spanning the late Meiji, Taisho, and early Showa periods).
