Tanzaku Chawan | Kenzan-Style | Iron-Star Black & Waka Poem White Panel | Kyō-yaki

In Japanese literary culture, the tanzaku (短冊) is a narrow paper card on which a poem is written — hung from bamboo branches at the Tanabata festival, exchanged between poets, preserved in albums of seasonal verse. For Ogata Kenzan (尾形乾山, 1663–1743), the great Kyoto poet-potter who was also a Rimpa school painter, the rectangular surface of a tanzaku became one of the governing compositional ideas of his ceramic practice: he would leave a white feldspar "panel" in the center of a bowl or jar, paint it with the flowing cursive script of a waka poem, and frame it above and below in iron black — transforming the ceramic surface into a three-dimensional poem card. This convention, passed through generations of Kyoto studio practitioners, is what defines the tanzaku-chawan (短冊茶碗).

This chawan works entirely within that inheritance. The upper and lower body carry a tessha-yu (鉄砂釉 — iron-sand glaze) of extraordinary density: thousands of fine iron particles suspended in the glaze fire to a deep blue-black scattered with micro-points of lighter tone — a surface that reads in direct light like a night sky filled with stars, and in soft light like dark water. Against this, a large rectangular white panel (shiro-yu 白釉, feldspar ash glaze) occupies the mid-body, its surface carrying a fine crackle network (kan'nyū, 貫入) of age. Within the panel, two diagonal lines suggest bamboo stems or autumn reeds (take 竹 / ashi 葦) — the Rimpa shorthand for the natural world reduced to gesture. Over and between these lines, columns of cursive hiragana (sōgana, 草仮名) read right to left in a flowing waka poem — the specific verse awaiting transcription by a calligraphy specialist, but its seasonal tone of wind, reeds, and passage clearly legible in the brushwork's rhythm. The outer foot ring carries an incised potter's cipher, scratched into the clay before firing. The clay body is pale sandy cream, consistent with Kyoto workshop material.

For the tea ceremony practitioner, a tanzaku-chawan places a moment of poetry inside the moment of tea: as the host presents the bowl, the guest reads the poem, and the two arts — chadō (茶道) and kadō (歌道, the way of poetry) — meet in a single object. For the collector, this bowl occupies the intersection of ceramic art and literary culture that defines Kenzan's legacy above all other Japanese potters. The iron-star texture and the white poem panel together constitute one of the most visually sophisticated compositions in the entire Chikoyaki collection.

Very good condition. Both glazes intact. Panel text fully legible. Crackle is natural. No chips, cracks, or repairs.
