Pre-Tokugawa period The site of Tokyo has been inhabited since ancient times. There have been multiple Paleolithic period (around 40,000–16,000BC.) sites found in present-day Tokyo. During the subsequent Jomon period, the Holocene glacial retreat caused sea levels in Tokyo Bay to rise by 120 cm, with the coastline running along the edge of what is now the Imperial Palace. Middens such as the Omori Shell Mounds still mark where the coast line ran in those days. The Yayoi period, during which agriculture spread across the country, is named after the Yayoi 2-chōme Site in Bunkyo, where the first example of Yayoi pottery was excavated in 1884 by Shozo Arisaka.
