Don’t miss the once-a-year display of the Sanada Family’s Important Cultural Heritage, the Aoe no Odachi! Wielded by Nobutsuna at the Battle of Nagashino, it is 103 cm long and weighs 1.5 kg, nearly twice that of a regular katana. Made in the Nanboku-cho era in what is now Kurashiki City, Okayama Prefecture, by the Aoe swordsmiths, this katana has chips in the blade.
