• Samurai helmets were used not only to protect the head, but also to express the dignity and status of the warlord. As time went by, helmets evolved in line with changes in warfare and came to play the role of expressing the individuality of the warlord. Through the types of helmets, helmet ornaments, and accessories (tachimono, masks, etc.), we can see that the strong faith and will of the warlord is expressed in the helmets.
