Stone Kilns on a Slope Above the Uwa Sea
The Former Misaki Refinery Kiln (旧三崎精錬所焼窯, Kyū-Misaki Seirensho Yakikama) is a group of stone copper-smelting kilns of the middle Meiji period built into a wooded hillside facing the Uwa Sea in the town of Ikata, Ehime Prefecture, and it was entered on the national register as a Registered Tangible Cultural Property on 1 December 2003. The notice of registration followed on 25 December that year. The Agency for Cultural Affairs records it as a single site of stone construction covering 496 square metres.
The kilns were used for the stage of copper working called arabuki, the rough smelt that separates crude metal from roasted ore. They are set out with their flues running up the slope, three ranks arranged in straight lines and two more curving with the contour. Ehime Prefecture's cultural properties listing counts 22 kilns in all.
Every firing mouth is turned as an arch about 0.9 metres across, built from the green schist that outcrops all over the Sadamisaki Peninsula and is known locally as aoishi, blue stone. The Agency for Cultural Affairs record names the material chlorite rock; the prefectural listing gives it as chlorite schist, the term a geologist would use.
A Short-Lived Industry, Recorded in Stone
Ikata Town's cultural properties page states that the refinery was established in 1900 by Yano Sōzaburō and closed in 1908, brought down by a collapse in the copper price and by attacks from local residents whose land and health had suffered from the smelter's fumes. The town's separate survey of the Misaki district is less certain about the start, saying only that the works stood at Dōjibana at some point before 1897 and that its founding date is unclear.
Either way the plant ran for at most a decade or two, employing 20 to 30 people. The Sadamisaki Peninsula held dozens of small copper deposits, and ore from those workings was carried here to be crushed, roasted and smelted in sequence. Three brick chimneys and scattered slag along the shore survive alongside the kilns.
That brevity is part of why the Former Misaki Refinery Kiln matters. Copper smelting in Japan modernised quickly at the great mines, and small provincial works of this kind were abandoned rather than rebuilt, so few of them left standing masonry. The registration criterion applied was contribution to the historic landscape of the country, and the Agency for Cultural Affairs describes the site as valuable evidence for how copper smelting was modernised.
What the Masonry Shows
The stonework is worth reading closely. Green schist splits into thin flat plates, and the builders used that property directly, laying the slabs flat in level courses without mortar so that the wall face reads as a dense stack of horizontal lines. Where an arch was needed, the same plates were set on edge and stepped round the opening.
The arches are the part that survives best. Each firing mouth keeps its curve, and against the layered horizontal courses around it the ring stands out sharply. Above and behind, the flue channels climb the slope, which is how the kilns drew without powered fans.
Trees have taken the site back. Young trunks now grow out of the collapsed upper courses of the Former Misaki Refinery Kiln, roots running along the tops of the walls, and leaf litter fills the fire boxes. The condition is unstable in places, and the loose stone gives way underfoot.
Access and How to See It
This is not a site with a car park, a path or an information board. The Former Misaki Refinery Kiln stands on private land on a steep wooded slope, and Ehime Prefecture records the owner as a private individual. There is no admission arrangement and no route maintained for visitors. Anyone hoping to see the kilns should contact Ikata Town Hall first, on 0894-38-0211, and should not enter the land without permission.
The address entered in the national database is 2085 Sada Otsu, Ikata-cho, Nishiuwa-gun. Note that the town's own pages place the works at Dōjibana in the Inoura district, so the two records describe the same site with different local names.
For visitors who cannot reach the kilns, the Sadamisaki Peninsula Museum at 293 Shionari Otsu in Ikata covers the peninsula's mining and industrial past along with its natural history. It opens from 9:30 a.m. to 5 p.m. with last admission at 4:30 p.m., closes on Mondays, and charges 300 yen for general admission. The telephone number is 0894-21-3400.
