A plastered strongroom at the north edge of the works
At the northern boundary of the Iwano Heizaburo Paper Mill stands a two-story earthen-walled storehouse, or dozo (土蔵), facing south. Built in the late Taisho period (1919-1926), it was raised to keep finished paper and valuables safe from fire and damp, the perennial enemies of any papermaker.
A lean-to porch shelters the front. The thick walls are finished in white plaster carried right up under the eaves (nurikome, 塗込め), with weatherboarding protecting the lower register. Extending southwest from the storehouse, a connecting wing, the tsunagiya (繋ぎ屋), links it to the Main House and holds service rooms including a bath.
Why it matters
The building was registered as a Registered Tangible Cultural Property in February 2021, part of the eight-building group entered under the criterion of contributing to the region's historical landscape. Where the production halls tell the story of making paper, the storehouse speaks to its value once made.
That value is not abstract. The mill's kumohada-mashi (雲肌麻紙), a hemp-and-mulberry painting paper developed by the first Iwano Heizaburo, allowed painters to build up thick layers of pigment in a way earlier papers could not. Sheets destined for artists such as Yokoyama Taikan were worth guarding, and a fireproof dozo is where such things were kept.
What to look for
The care in the construction shows. The east side of the upper floor holds a formal room with a tokonoma alcove (zashiki, 座敷), an unusually refined touch for a working storehouse and a sign of the household's standing. The plaster, the boarded skirt and the low porch all read as deliberate rather than merely functional.
Seen from the lane, the white-walled dozo tightens the northern frontage of the compound and sets off the darker timber of the Main House beside it. It is best appreciated from outside, as part of a visit to the working mill, which offers tours by arrangement.

Q&A
- What was the storehouse used for?
- As a fireproof earthen-walled dozo, it protected finished paper and valuables from fire and moisture. The attached connecting wing linked it to the Main House and held service rooms such as a bath.
- When was it built?
- In the late Taisho period, roughly 1919 to 1926, the same span in which the adjacent papermaking and pressing hall went up.
- Is there anything unusual inside?
- Yes. The upper floor has a formal tatami room with an alcove on its east side, a refinement rarely found in a plain storehouse and a mark of the family's status.
- Can I visit?
- The storehouse is part of an active workshop and is best seen from the lane. The mill runs tours and sutra-copying experiences by prior arrangement.
