Japanese blue and white porcelain octagonal leaf bowl, decorated in underglaze cobalt with a leaf and chrysanthemum pattern. The form is footed and factory-molded, with a clean white ground and deep blue reserve areas; no maker’s mark is visible, so the piece is described by form and decoration rather than attribution.

• Octagonal bowl form with a small foot and rounded profile.
• Blue and white underglaze decoration with leaf and chrysanthemum motif throughout.
• Porcelain body with glossy glaze and crisp painted linework.
• No backstamp, signature, or factory mark is visible in the photos.
• Origin is not marked.
• Shown as photographed; one bowl included.

Made as a serving or display bowl, it would work today as a collectible tabletop piece, a small serving bowl, or a decorative accent in a Japanese ceramics collection.
