Comparison of regions of Japan
Since the late-7th century, the Tōkaidō region or "Eastern Sea Circuit" was made up of 15 provinces on the Pacific Ocean from Sendai Bay to Kinai. Fuji-san, Tokyo, Yokohama, and other important or well-known places are in this region. Tōkaidō also names a road which connects the provincial capitals of this region on the island of Honshū.
