Vintage Japanese Bizen Ware Flask Vase, Inomata Masaaki, Signed Stoneware

Some Bizen ware arrives unattributed; this piece doesn't have to. The incised mark on its base matches the registered kiln seal of Inomata Masaaki, a Bizen potter born in Osaka in 1948 who trained at a ceramics school in Aichi Prefecture, studied further at Shikoku Otani and the Bizen kiln Tōshōen, and struck out on his own in 1975 — buying a wood-burning noborigama kiln and firing his first independent batch of Bizen ware, which was covered in the press and sold at strong prices from the start. Over the decades since, his work has been selected for the Okayama Prefecture Art Exhibition and the Chugoku Regional Traditional Crafts Exhibition, recognized at the Bigeikai Exhibition, and in February 2008 he was formally certified as a traditional craftsman.

The vase itself takes an unusual form for Bizen ware: flattened into a soft, rounded pillow shape with a narrow neck and two small loop handles at the shoulders — a design lineage tracing back to portable travel flasks meant to be slung by cord over the shoulder, reimagined here as a standalone decorative vessel. As with all Bizen work, no glaze was ever applied; the deep wine-red to near-black surface and the striking patch of golden, finely speckled goma near the base were produced entirely by wood ash and flame over roughly a week of continuous firing, working directly on Bizen's iron-rich local clay. The interplay of dark and light across the body is the kiln's own signature, unrepeatable by design.

For a collector, the combination here is what matters most: an unglazed Bizen piece with genuine sculptural presence, made by a named, exhibition-recognized potter whose kiln seal can be independently verified — a rare pairing of striking form and confirmed authorship in a category where so many pieces circulate without either.

Shipped with care from our studio in Hanoi. Natural ash marks, surface texture, and firing variation are original to the piece and central to its value as a wood-fired Bizen work.
