A New Kind of Consumer Space
Reimagining space--how bodies engaged with structures--was the key to the transformation of Echigoya, a Tokugawa era dry goods store, into Mitsukoshi, pioneering modern department store (百貨店 hyakkaten or デパート depaato) in Japan.
In the Tokugawa era, customers would wait sitting in an open interior space while a clerk searched out goods to satisfy their needs and tastes. As was and is Japanese custom, customers would take off their outdoor footwear before entering the interior and wear slippers.
Yet a central aspect of a Western style department store experience was that customers did not have to wait for or depend on clerks for access to commodities. Rather, they could walk around freely to peruse displays and even to touch some goods. Permitting customers to wear outdoor footwear indoors violated Japanese sensibilities, so it took time and transitional measures to finally arrive at the open access interior taken for granted today. Some experiments included: sitting at a counter open to the exterior with clerks bringing goods; having a divided interior, one portion reserved for clerks serving customers in the old way, and another for cases that customers could walk around; and having customers switch into slippers to walk around at will among various counters and displays. The latter practice ended when Mitsukoshi inadvertently misplaced the footgear of a large crowd of customers.
The physical transformation of the retailer was not only inspired by the close study of specific Western department stores, such as Harrods or Bon Marche. It participated in the growth of a Japanese "exhibitionary complex," a term coined by Tony Bennett in The Birth of the Museum. The complex included expositions and museums to kickstart such domestic modernizations as industrialization and the inculcation of a sense of belonging and mobilization in the newly conceived Japanese nation. To further explore this late nineteenth and early twentieth century exhibitionary complex, a visit to the National Diet Library's digital presentation "Expositions" is highly recommended.
For a basic timeline, Mitsukoshi provides a corporate history spanning the late seventeenth to the twenty-first century. War and empire, however, do not make much of an appearance in this timeline. Wikipedia provides a more compartmentalized but detailed account.
