Founding Sogo: from a used-clothing stall to a Shinsaibashi department store (1830)

How a house that began in used goods reached the stock exchange

What this founding shows is the meaning of starting the business not on the front street of new kimono goods, held by long-established houses, but on the low-barrier back street of furute — used clothing. In front of the Ikasuri shrine, where pedlars and brokers brought their goods together, the first Sogo Ihei built up credit and capital little by little without much of a stake, and that accumulation was handed down through three generations. A plain trade in everyday clothes laid the foundation of the merchant house that would later become a department store. Precisely because it set out from a low place, there was room left for the next generation to raise the format.

The other thing visible here is that Sogo changed shape through two conversions of format. The fourth Sogo Ihei moved into new kimono goods in 1877, and incorporation in 1919 brought in Western clothing and sundries and carried the house on into a department store: two stages that redirected the trading area and the funds built up in used clothing, in order, toward higher-priced ground. Yet the large investments in the Shinsaibashi flagship and the Kobe store also became a burden on the balance sheet, and were one reason the founding family withdrew from management in 1935. The road from a low-entry used-clothing house to a listed company ran on two wheels at once — raising the format step by step, and securing the capital to pay for it.
