The visor was made after not a legendary or historical man of bravery but Moritomo TANI, who was a person existing at that time, and it was so valuable that it could be used in another family as an award and the person who received was happy with it.
伝説歴史上の剛勇な人物などではなく、当代の人物である谷衛友にわざわざ似せて作られた頬当て(仮面)という品であり、それが他家で恩賞として使われるほど価値があり、貰ったほうも嬉しい。
