The last in a series of feudal rulers of Japan was the Tokugawa family. They re-united Japan in 1603, after centuries of civil war, ushering in an era of 265 years of peace in Japan. During Edo period rule (1603 - 1868), Japan’s economy and culture flourished. A cadet branch of the Tokugawa House was made lords of what is now Wakayama Prefecture, building Wakayama Castle. The 8th Tokugawa shogun, Tokugawa Yoshimune (1684 - 1751), who was a native son of Kishu Domain (modern-day Wakayama), ruled Japan from 1716 to 1751, and is considered one of the greatest of the Tokugawa Shoguns, presiding over many important reforms. Echoes of the feudal period remain throughout Wakayama, be it a traditional inn at Ryujin Onsen built by order of the lords of Wakayama that still operates, or to the maintenance of the famed Kii Mountain pilgrimage routes.
