Koyama Munetoshi(\u56fa\u5c71\u5b97\u4fca) produced swords for only about 15 years, making his works extremely rare today. This Katana is in good condition and is a valuable example of his limited surviving pieces.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

        Katana Certificate of Authenticity and Registration<\/h2>\n

        This Katana has been certified as a Hozon Token (\u4fdd\u5b58\u5200\u5263)<\/em> by the NBTHK (Nihon Bijutsu Token Hozon Kyokai), Japan\u2019s most prestigious sword appraisal organization.<\/p>\n

        A Hozon Token<\/em> (\u4fdd\u5b58\u5200\u5263) is a Japanese sword that has been officially designated as “worthy of preservation” based on its historical value, craftsmanship, and overall condition.<\/p>\n

        The official certificate is included in the set.<\/p>\n

        All Real Katanas are registered with the Board of Education of the prefecture in which they are located.<\/p>\n

        Please note that the original registration certificate must be returned to the Board of Education prior to export, but a copy will be enclosed with your purchase.<\/p>\n

        1. Toshin(\u5200\u8eab)<\/h3>\n

        \"\"<\/p>\n

        The Toshin<\/em> refers to the entire blade of the Katana.<\/p>\n

        When evaluating a Katana, the blade\u2019s length\u2014and particularly its sori<\/strong> (curvature)\u2014is a key point of appreciation.<\/p>\n

        The sori<\/em> is what enables the Japanese sword to remain unbreakable and unbendable, while also allowing it to cut through objects with remarkable efficiency and minimal force.<\/p>\n

        If you’re interested in the scientific background of this, we explain the theory in detail in the following article:<\/p>\n
