The Oldest Building on the Site
Of the five registered structures at the former Tanaka Family Residence, the south storehouse (minami-dozō) is the one that was already standing when the rest went up. It dates to 1892, the twenty-fifth year of the Meiji era, a generation before the main house and its companions of around 1919. When the Ōmi merchant Tanaka family rebuilt the compound in the Taishō era, this earlier storehouse was kept and worked into the new plan.
The family traded as Tagen in hemp cloth and mosquito nets, a business begun in Echigawa in 1818 that reached Kyoto and Tokyo over three generations. A storehouse was where such a household kept goods and valuables secure, and its thick, fire-resistant walls were built to protect them. The south storehouse stands just south of the corridor linking the main house to the great hall. It is a two-storey dozō, plaster over a timber frame, about 8.1 metres by 4.7 metres, roofed in a gabled, gable-entered form (tsuma-iri) clad in pantile, with a footprint near 38 square metres.
Plaster Worked Like Sculpture
What sets the south storehouse apart is its plasterwork. Storehouse walls are the province of the sakan, the plasterer, and here the trade is pushed toward display. The west entrance is framed in white plaster shaped into scrolling plant motifs and the Tanaka family's measure crest, the "one-shō" mark carried by the Tagen house. On the east gable, a round window is capped by a plaster eave modelled into an undulating gable form (karahafu), a flourish more often seen on temple gates than on a merchant's storehouse.
These are wet-plaster reliefs, built up and carved while the material was workable, and they show a plasterer confident enough to treat a utilitarian wall as a surface for ornament. The effect is measured rather than loud: a working storehouse whose openings are marked, at the points that catch the eye, with careful modelling.
The building was registered under a different criterion from the main house and tea room. Where those were listed as models of design, the south storehouse was recognised for contributing to the historic landscape of the nation (kokudo no rekishiteki keikan). Its value lies in how, together with the north storehouse, it helps hold the older character of the streetscape along the Nakasendō.
What to Notice
The residence now runs as Ōmi Shōnintei, a reservation-only restaurant serving Lake Biwa freshwater fish and seasonal dishes, in business since 1994. Because the storehouse sits within a working compound rather than a museum, the way to appreciate it is to read its exterior, the two faces where the plasterer left his best work.
Look at the west entrance and trace the scrolling motifs and the measure crest worked into the door frame. Then find the east gable, where the round window and its wave-formed plaster eave sit above. As the earliest building on the site, in place before the Taishō rebuilding gave the compound its present shape, the south storehouse anchors the residence to the Meiji years of the Tagen family's rise.

Q&A
- Why is the south storehouse significant?
- It is the oldest of the five registered buildings, dating to 1892, and it carries some of the site's finest plasterwork, including a wave-formed eave and a family crest worked in white plaster.
- What is a dozō?
- A storehouse built with thick, fire-resistant plaster walls over a timber frame, used by merchant households to protect goods and valuables. The south storehouse is a two-storey example.
- What is the crest on the door frame?
- The record describes the Tanaka family's "one-shō" measure crest, worked in plaster alongside scrolling plant motifs at the west entrance. The family traded under the name Tagen.
- How is it protected?
- As a Registered Tangible Cultural Property, listed in 2008 for contributing to the historic landscape, a criterion recognising its role in the streetscape.
- Can I see the plasterwork up close?
- The building stands within the restaurant compound, so access is as a dining guest by reservation. Its most rewarding features are on the exterior west and east faces.
