(③). The fire began on the
eighteenth day of the year, in Edo's
Hongō district, and spread quickly through the city, due to hurricane-force winds that were blowing from the northwest. Edo, like all Japanese cities and towns at the time, was built primarily from wood and paper. The buildings were especially dry due to a drought the previous year, and the roads and other open spaces between buildings were small and narrow, allowing the fire to spread and grow particularly quickly. (Many cities in Europe had similar problems, being built of flammable material and tightly packed; the
Great Fire of London nine years later was of similar magnitude.) Though Edo had designated
fire brigades, the
hikeshi, it had been established only 21 years earlier, and was simply not large enough, experienced enough, or well-equipped enough to face such a
conflagration. On the second evening, the winds changed, and the fire was pushed from the southern edges of the city back towards its center. The homes of the shōgun's closest retainers in
Kōjimachi were destroyed as the fire made its way towards
Edo castle, at the very center of the city. The
main keep, most of the outer buildings and all of the retainers' and servants' homes were destroyed. Finally, on the third day, the winds died down, as did the flames, but thick smoke prevented movement about the city, removal of bodies, and reconstruction for several more days. ==Aftermath==
