Water and commerce in everyday Edo
Look beyond individual homes to the systems supporting a large city.
Water connects Edo beneath its streets
Did an aqueduct mean every home had a tap?

A route brings water into the city.
A large city needs a route for drinking water
Edo’s water systems brought water into the city. A nearby river did not make drinking water available everywhere; sources had to be connected to places of use.

Tokyo Waterworks: Edo water supply ↗Life beyond the tenement room
A tenement’s shared water point need not have drawn only the groundwater directly beneath it. Edo distributed water from distant sources through conduits beneath the town. Lifting a bucket depended on intake, channels, distribution and repair. The everyday life of the crowded city extended well beyond an individual room.
Closely spaced timber buildings made fire and access important shared concerns. Gates, watch posts and observation facilities connected homes with neighbourhood management. Modern self-contained domestic arrangements cannot simply be projected onto an Edo room.
Bringing water into the city
Planning began in 1652, the channel was excavated in 1653, and underground distribution supplied neighbourhoods in 1654. The open route to Yotsuya and the pipes beyond it performed different stages. Reaching the city’s edge did not complete distribution.
Gravity required attention to heights and gradients. Proximity to a river alone did not ensure supply. Engineering linked the intake, trunk channel and distribution, placing a long chain of work behind ordinary water use.
Supplying shops by sea and river
Nearby production combined with distant shipping. Cotton, oil and paper from the Kamigata region linked Edo consumption to work elsewhere. Unloading and onward transport connected seaborne cargo with river routes and streets before products reached shops.
Channels and vessels still required maintenance and people to handle and sell goods. Edo combined consumption with organised supply. Following a meal or purchase back towards sources reveals both the city’s variety and its dependence on outside labour.
