Vintage Japanese octagonal porcelain vase / Signed Bottom ~ Bin R

This vase was made during the Mid-Century modern era, specifically between the 1960s and 1970s.During this postwar period, Japanese porcelain manufacturers like Toyo and Yamaji mass-produced high-quality ceramic wares heavily tailored for the Western export market. Designers blended traditional Japanese motifs—such as the hand-painted black and brown bamboo—with trendy mid-century geometric shapes, resulting in the distinct octagonal form of this piece.
