Modern Authentic Japanese Sword Tanto Signed by Gassan Sadakatsu with NBTHK Tokubestsu Hozon Certificate 【Description】 Summary This blade was signed by Gassan Sadakatsu (月山貞勝) in the 15th year of the Shōwa era (1940), a commemorative year marking the 2600th anniversary of Japan’s imperial lineage, based on the mythical founding of the nation by Emperor Jimmu in 660 BCE. Gassan Sadakatsu was born in 1869 (2nd year of Meiji era) in Osaka’s Yariyamachi district as the eldest son of Gassan Sadakazu (初代貞一), a renowned swordsmith and Imperial Court Artist (Teishitsu Gigeiin). From a young age, he studied under his father, learning both sword-forging and the art of decorative carvings (horimono). Although he remained largely in the background during his father’s lifetime, Sadakatsu became active mainly from the Taishō period into early Shōwa, during which he forged numerous swords by imperial commission and for the Japanese Army and Navy. His works are distinguished by their mastery of various traditional sword-forging styles, including the famed “Ayasugi-hada” (綾杉肌)—a unique, wave-like forging pattern passed down through the Gassan school. Many of his blades also feature intricate and powerful carvings. Sadakatsu’s contributions extended beyond his own craftsmanship. He trained several exceptional smiths, including his son Gassan Sadakazu II (二代貞一) and Takahashi Sadatsugu, both of whom were later designated as Living National Treasures (Ningen Kokuhō). His influence and skill were officially recognized by the Osaka Prefecture, and it is said that news of his passing in 1943 at the age of 70 was announced with a special edition newspaper. The History of the Gassan School The Gassan lineage of swordsmiths dates back to the early Kamakura period, with Giohmaru, its legendary founder, who worked at the base of Mt. Gassan in Dewa Province (present-day Yamagata Prefecture). The school flourished throughout the Kamakura and Muromachi periods, developing its iconic Ayasugi-hada pattern—flowing, wave-like grain structures seen prominently on Gassan blades. Although the school’s prominence diminished somewhat during the Edo period, its reputation remained. The famous poet Matsuo Bashō even referenced Gassan smiths in Oku no Hosomichi (The Narrow Road to the Deep North), attesting to their enduring fame. In the late Edo period, Gassan Sadayoshi relocated to Osaka and revitalized the tradition, establishing what came to be known as the Osaka Gassan line. This revival led to a succession of highly skilled smiths including Gassan Sadakazu (the elder), Gassan Sadakatsu, and Gassan Sadakazu II, who continued the family craft despite modern challenges. Today, the Gassan legacy lives on through Gassan Sadatoshi and his successor Gassan Sadahito, who carry forward this centuries-old tradition of Japanese sword craftsmanship. This blade is appraised as a Tokubetsu Hozon Token (特別保存刀剣) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, especially well preserved and high quality with artistic value. *Please keep in mind that there is a tiny Kitae Kizu on this blade.
