Trading at each port aboard a kitamae ship

Freight and trading are different businesses

Kitamae owners bought and sold their own cargo rather than relying only on freight charges. Herring used as fertiliser in western Japan and used clothing sold northwards met different regional demands. Safe navigation and decisions about where to buy and sell jointly determined the results of a voyage.

Ports enabled unloading, storage and renewed loading, linking sea routes with production and urban trade. A single line between Osaka and the north identifies a route while omitting intermediate business. The voyage depended on more than its endpoints.

Kawamura’s western route of 1672 extended sea transport around Shimonoseki toward Osaka, differing from transshipment through Tsuruga and Lake Biwa. Route choice affected handling and trading opportunities.

Kitamae identifies routes and business while benzaisen describes vessel form. Ishikari distinguishes Edo-period activity at Matsumae ports from local contractor vessels. Similar ships did not automatically undertake identical trade.

Different uses create price differences

Herring from Hokkaidō found demand as fertiliser for cotton in western Japan, while used clothing travelled north. Regional differences in production, supply and use created trading opportunities. Treating every marine cargo simply as food misses why some goods moved such long distances.

Trading on both legs was called saw-like trading. Buying cargo did not guarantee profit: a lower selling price reduced returns, and shipwreck threatened goods and lives. Successful owners’ houses show outcomes, while price risk and maritime danger explain the conditions of earning them.

Wealth and labour in port towns

Merchant buildings, handling sites, votive ship pictures and festivals preserve different traces of the routes. Movement of people also transmitted practices, but similar festivals do not establish a single ship or year of transmission. Separate dates and records reveal overlapping exchanges.

An owner’s house documents accumulated wealth, not every sailor’s earnings. Navigation, handling and selling involved different positions. Distinguishing ownership, work and exposure to danger turns a streetscape from a list of grand buildings into evidence for transport, commerce and labour.
