Kakunodate is a former castle and samurai town. Though the castle no longer remains, its samurai and merchant districts are relatively unchanged from its founding in 1620. Well preserved former residences that now serve as museums offer a glimpse into the samurai lifestyle. The Aoyagi House, with its thatched roof, is one of the most interesting. The Ishiguro House has a collection of samurai armor and clothing on display. The bullet train from Tokyo Station to Kakunodate will take a little over 3 hours.
