Seizan Japan Mid-Century Modern Cobalt Blue Fluted Vase with Red Pinstriping

This is a vintage Japanese ceramic vase produced by Seizan. The item features a tall, cylindrical form with a distinct lobed or fluted body, standing approximately twice the height of a standard 12oz soda can shown for scale. The primary glaze is a deep, high-gloss cobalt blue that appears almost black in certain lighting, characteristic of high-quality Japanese porcelain exports from the mid-to-late 20th century. A striking design feature is the inclusion of thin, vertical red pinstripes that follow the recesses of the fluted edges, providing a sharp geometric contrast. The construction shows precise molding and uniform glaze application. Based on the 'Seizan Japan' attribution, this piece likely dates to the 1960s or 1970s and reflects the Mid-Century Modern influence on Japanese decorative arts. The surface appears to be in good vintage condition with a reflective sheen, though there is a visible small white fleck or glaze skip on the left-side center that may be a manufacturing imperfection or a minor surface nick. No significant cracks or large chips are immediately apparent. The craftsmanship indicates a commercial but high-quality kiln production, emphasizing sleek lines and minimalist aesthetics typical of the 'Japan' marked wares meant for international markets.
