Kobukuro Kiln (Onta pottery)

Sarayama, Hita City, Oita Prefecture, Kyushu

Onta ware has been made, unchanged, for roughly 300 years by just nine kiln families in an isolated mountain hamlet, using techniques transmitted only from father to son (“isshi-soden”) and never taught outside the village. Every kiln stamps its work simply “Onta-yaki” – no individual maker’s name appears – and it is Onta ware as a whole, rather than any single artisan, that is designated a national Important Intangible Cultural Property. The village’s signature “tobi-kanna” technique presses a springy metal blade against the spinning clay to leave a continuous chattered, faceted pattern. Kobukuro Kiln is one of Onta’s nine kilns.
