Edo was nothing more than a village on the edge of Edo Bay when Ieyasu Tokugawa chose it as the site for a castle from which he, as shogun, could administer the country. The castle was of utmost importance because Japan had just emerged from a hundred years of civil war, and Ieyasu was determined that the power he had gained should not be wrested from him by antagonistic warlords. The castle, of course, had to be supplied with the necessities of everyday life, and thus a town had to be built where merchants and artisans could live. It is the planning and construction of Edo Castle and the town that would support it that lie at the core of this book. In fact, the construction of the city would be an ongoing process throughout its 260-year history, in the wake of repeated devastation by fire and earthquake and under the pressure of an ever-expanding population.

Another aspect of the book concerns Edo's cultural life, which moved over time from classical conventions dominated by the samurai to the more popular and lively forms favored by the merchants and artisans. Featured here are temples and shrines, festivals, bath houses, pleasure quarters, kabuki theaters, street gangs, the poet Basho, sumo wrestling, side shows, ukiyo-e prints, barbers, and much more.
