Japanese Blue and White Porcelain Square Bowl with Leaf Motif

This is a small, square-shaped porcelain bowl, likely of Japanese origin, featuring a distinct blue and white underglaze decoration. The bowl measures approximately 4-5 inches across based on the visual context. Its shape is not perfectly round, but rather has gently curved sides that hint at a squared or quatrefoil form, contributing to its artisanal appeal. The primary decorative motif consists of large, stylized leaves rendered in white and a lighter, off-white hue against a vibrant, cobalt blue background. The leaves are outlined and detailed with fine blue lines, suggesting veins and contours, showcasing a traditional East Asian aesthetic often found in 'sometsuke' (blue and white) ware. The interior and exterior surfaces of the bowl are adorned with these leaf patterns, creating a cohesive visual design. The rim of the bowl appears to have a slightly irregular, hand-formed quality, adding to its uniqueness. The porcelain body has a smooth, glazed finish, and the blues vary slightly in intensity, indicating hand-painting rather than a uniform machine application. The condition appears to be good, with no immediately visible chips, cracks, or significant wear. There might be some minor surface irregularities consistent with handmade ceramics. The bowl sits atop a separate, dark-colored, possibly wooden or ceramic stand with openwork details, which is not part of the bowl itself but suggests it was displayed with care. The craftsmanship suggests a mid-20th century or earlier origin, typical of export ware or domestic production intended for everyday use or decorative purposes. The quality of the hand-painting, particularly the delicate outlining of the leaves, indicates a skilled artisan.
