Odawara Castle
Odawara, where his home castle Odawara Castle (小田原城) was located, was gradually transformed into an important trading center by modifying the region's throughways (which were hitherto designed with Kamakura as a hub) and creating an artisan's guild within the castle town. In addition, post stations and market places sprung up throughout the Hôjô's lands. Ujiyasu soon became one of the main powers in the Kantō region.
