Heian Japan
Heian Japan appears on the map from 793 to 1187. At its greatest recorded extent, in 1094, it covered about 243,639 km².
One of the realms of Imperial Japan (Yamato to Kamakura). From around 250 CE, the age of great keyhole-shaped burial mounds, the Yamato kings of the Nara basin gradually brought the clans of central and western Japan under their rule. Adopting Buddhism, Chinese writing and Tang-style law codes between the 6th and 8th centuries, they became emperors governing from planned capitals at Nara and, from 794, Heian-kyo, now Kyoto.
