Tokyo by Sofia

Where is Tokyo? Why
was it built where it is?
Tokyo is on the northwest end of Tokyo
Bay on the Kanto plain, Japan`s largest lowland. On one side (NE)
is the Edo river and on the other side is the Tama river. Edo was
the first name of the city after the powerful Edo family. In 1457
a warrior named Ota Dokan built a stone fort on a hill.The stone
fort protected people from enemies and there was also a harbor
for ships. Tokugawa Ieyasu made it a city.
