I don't know why they would call it a "ruin"; it's been restored quite well. Nice parc area around it that you can walk through and sit at for free. Large Koi in the moat - sometimes you cannot see them due to Algae in the summer.
Springtime is nice around the castle as the numerous cherry tree blossoms are out - then it is time for a picnic with O-Sake! There is a shrine nearby on the north-west side of the castle.
