Iwachu cast iron kōro incense burner with sakura lid by Nanbu Tekki Iwate, Shōwa period

€95.00

The weight of cast iron is its first greeting. Three short legs, a round belly, and a lid cut through with a five-petalled flower. The iron has darkened over the decades into a warm reddish brown that photographs cannot quite capture, and the casting texture catches the light in a way that makes the surface look almost alive. This is the kind of object you pick up and do not immediately put down.

This koro was made by Iwachu (岩鋳), Morioka's most recognised ironware foundry and one of the defining names in the Nanbu Tekki tradition. That tradition has its roots in the mid-17th century, when the ruling Nambu clan invited a Kyoto kettle-maker north to produce vessels for the tea ceremony. Iwachu has been part of that lineage since 1902, and its foundry stamp carries enough weight that the company explicitly warns buyers against imitations.

What makes this kōro special

The look and feel up close

The body is not uniformly brown. Up close, the casting shows a subtle mottled surface, paler in some areas, deeper in others, where the iron met the mold and cooled unevenly. It is the texture of something made, not manufactured.

The lid sits flush with a satisfying weight, and the open sakura petals are not decoration but function: when incense burns inside, the smoke finds its way out through the flower and drifts upward in threads. The knob on top is cast as a small bud, compact and smooth against the rougher surface below.

Charming details

The sakura motif was not chosen arbitrarily. In Japanese design, the cherry blossom has long been used on objects connected to the ceremony of daily life: textiles, lacquerware, ironware.

On a koro, a vessel whose purpose is to carry something fleeting upward, a flower that blooms for only a few days is quietly fitting.

This particular cut pattern is typical of Shōwa-period Iwachu production, where the open-work lid served both to let the smoke escape and to display the foundry's skill with negative space in cast iron.
