We didn't much time to hang around in Sendai, and only got less than one day. The only pick for us, without regrets, is a visit of Mount Aoba and Aoba Castle. The walk up to the ruins of its outer walls isn't tough. The best reward, besides the greenery along the path, is the sweeping views of the cityscape below. You will also be impressed by the statue of Date (pronounced dah-tay) Masamune in armour and on horseback. In case you find Date's helmet somewhat familiar, it's likely because it inspired Darth Vader's helmet in Star Wars.
