This blade was a heirloom of the Sakai Saemon no Jō family, which ruled the Shōnai fief in Dewa
province. It was then worn by its descendant, Navy RearAdmiral Sakai Tadatoshi (18571943),
holder of the Fourth Court Rank Second Grade, the Order for Distinguished Service Third Grade,
and the Order of Merit Fourth Rank. Tadayoshi had this heirloom Ichimonji sword shortened
when he had a meeting with Emperor Meiji on the occasion of being appointed Residential
Naval Officer of the Japanese legation to Russia in 1901 in order to wear it with a court dress.
