Inuyama-jo Castle dates from 1440 and is Japan`s oldest castle. The castle is extremely important as it is preserved in its original state and hasn`t been rebuild like other castles destroyed during war which is a rarity in Japan. The castle costs 400 yen to enter and is open from 9 am to 4.30 pm. The castle is recommended for its beautiful view across the Kiso-gawa river from the top storey. The castle is a 15 minute walk west of Inuyama-yuen station.
