Bizen Yaki Tsutsugata Hanaire | Yamamoto Yūichi | Showa | Hi-iro Sangiri Anagama

Bizen (備前焼) is Japan's most uncompromising ceramic tradition. No glaze has ever touched a Bizen vessel — only iron-rich clay from the Inbe district of Okayama Prefecture (備前市伊部), wood fire sustained over ten to fourteen days in an anagama (穴窯) tunnel kiln, and the complete surrender of outcome to flame and atmosphere. The potter controls placement, temperature, and stoking rhythm. Everything else — every color, every texture, every transition of tone across the surface — is written by the kiln. This is yaki-jime (焼き締め) at its most rigorous, and it is why Bizen has been numbered among Japan's Nihon Rokko-yō (日本六古窯 — Six Ancient Kilns) since the Heian period. The post-war Showa revival transformed Bizen from a folk tradition into a fine-art discipline, as studio potters working in the lineage of Living National Treasure Kaneshige Tōyō (金重陶陽) reclaimed the kiln's ancient vocabulary with individual artistic intent.

This tsutsugata hanaire (筒形花入 — cylindrical flower vase) is a signed studio work by Yamamoto Yūichi (山本雄一), a Showa-period Bizen studio ceramicist. The signature is written in iron-oxide brushwork directly onto the raw clay base before firing — the classical fude-gaki (筆書き) practice by which a Bizen potter declares personal authorship. A secondary incised kiln mark (kizami, 刻み) — three parallel diagonal strokes cut into the clay before firing — accompanies the signature, identifying the piece's position within the anagama batch. Together, these marks confirm this is an intentional studio work, not workshop production.

The cylindrical form is resolved with quiet confidence: straight walls rise from a flat unglazed base, the shoulder narrows subtly, and the wide rim opens cleanly — a silhouette that refuses ornament and lets the fire speak. Three of Bizen's canonical fire effects are present in conversation. Hi-iro (火色 — fire-scarlet) saturates the upper body and shoulder in warm red-brown where the anagama's direct flame touched the clay. Sangiri (桟切 — blue-gray reduction) appears dramatically across the lower body, where oxygen was trialled out during the slow cool-down — the most prized and least predictable of Bizen's atmospherics. Goma (胡麻 — sesame ash) scatters golden-olive deposits across the mid-section, where burning pine ash landed, melted, and fused into the clay surface. A darker oxidation band at the rim records the final moments of the firing cycle. No two sides of the vase carry the same atmosphere — the anagama rotates its narrative around each piece.

The tsutsugata is the preferred form for nageire (投げ入れ) ikebana — free-thrown stems dropped loosely into the vessel in the spirit of jiyūka (自由花), the style championed by the Ohara school. A single branch of plum blossom, a stem of dried grass, or a spray of autumn leaves placed in this vase requires no floral foam, no mechanics — the rough clay surface holds the stem at the angle the hand releases it. For the collector, a signed Showa Bizen studio piece with full fire narrative is a document of both the kiln's ancient fire and one craftsman's hand and name.

The vase is in excellent structural condition — no cracks, chips, or repairs. All surface marks are authentic fire effects. Base clay shows natural age-appropriate wear. Signed and kiln-marked.
