1986 Neuromancer cover by Barclay Shaw

A narrow borderland of older streets, dividing Chiba Port and city (not clear if the city is Chiba City or Tokyo). It has no official name.

Life in Night City is an intense and fast race for survival of the fittest; its black market has a fragile "tension" that requires an intricate protocol. Whether business became careless, lazy or slow, or too fast and daring, it is an unforgiven mistake. Those ending up dead, end up in the clinic tanks as organ transplants.

Ninsei is its center. Cheap Hotel and the cheapest coffins (capsule hotels) are those nearest the port, beneath the quartz-halogen floods that light the docks.
