Overview A Japanese tea bowl (chawan) in warm reddish glaze, accompanied by its original wooden storage box (tomobako). The box is inscribed in brush calligraphy and bears a red seal, indicating that this piece was intended for tea-ceremony use and carefully preserved as a complete set. Tea Ceremony Context This form and glaze are characteristic of Japanese tea bowls made for chanoyu practice. The slightly irregular rim, compact body, and spiral-cut foot reflect hand-throwing and intentional asymmetry, elements valued in tea aesthetics for tactile and visual balance. Material & Technique Material: glazed pottery / stoneware Technique: wheel-thrown, hand-finished Glaze: iron-rich reddish glaze with natural pooling and firing variation The surface shows kiln-fired texture rather than decorative painting, consistent with studio tea wares. Markings & Box Wooden box (tomobako): handwritten calligraphy and red seal Bowl: spiral-formed foot ring, no modern factory marks The inscriptions are presented as visible in the photographs. No definitive artist attribution is claimed beyond the physical markings shown. Period Based on form, glaze character, and the use of a signed tomobako, this piece is likely Shōwa period (mid–late 20th century) studio pottery rather than Edo or early Meiji. Dimensions (approx.) From the measurement photos: Diameter: approx. 9 cm Height: approx. 6.5 cm Condition Good vintage condition. Minor surface variations, firing marks, and natural glaze irregularities are present, consistent with handmade tea ceramics. No cracks or repairs observed.
