Sendai City, situated in the center of Miyagi Prefecture, is the largest city in the Tohoku region(the northeastern region) and has prospered as the capital of the Dates' fief since Date Masamune reigned over this district and built the Aoba Castle at the beginning of the 17th century. Now, the neighborhood of Mt. Aoba, where you can find the ruins of the Aoba Castle, has been transformed into a park for the people of the city to rest and relax.
