Vintage K S Japan Blue Lusterware Tea Set

A set of Japanese lusterware ceramics featuring a vibrant cerulean blue glaze with an iridescent finish. The set includes four dinner plates, a coordinated saucer, and a matching teacup. The design motif consists of white cherry blossom (sakura) flowers on black branches, accented with small white dot clusters. The teacup exhibits a classic low-profile shape with an arched handle, while the plates feature a shallow well and rounded rims. The luster finish creates a metallic, pearlescent sheen that reflects light across the surface. Notable condition issues include minor shelf wear and visible glaze imperfections along the rims of the stacked plates, typical of mid-century Japanese ceramics. The bottom of these items typically bears the 'K S Japan' mark, a designation associated with post-WWII manufacturing (circa 1950s-1960s). The craftsmanship indicates a mass-produced but decorative assembly-line ceramic style, known for their thin, lightweight porcelain bodies and eye-catching reflective glazes. There is some protective plastic film visible over the teacup, suggesting recent handling or storage protection.
