A Katsukuni Katana (伊豫大掾橘勝国作)

The name Katsukuni – meaning ‘victorious country’ – was bestowed upon this smith by the powerful Maeda daimyô family of Kaga province, whose seat was the castle town of Kanazawa. The first generation’s father, Ieshige, had already established the shintô Darani school as a serious force in Kaga smithing, but it was Katsukuni who elevated the lineage to national prominence. Through the patronage of chancellor Yotsuji Yoshiie and the recommendation of the Maeda family, he received the honorary court title Iyo no Daijô and adopted the clan name Tachibana, tracing his lineage – on whatever basis – to the 17th generation Rai Kuniyoshi. The Katsukuni line ran for seven generations until the Meiji era.

This katana was forged in August 1670, the tenth year of the Kanbun era, and bears the full late-career signature of the first generation – a bannen mei recorded in the prestigious Fujishiro Nihon Shintô Jiten reference book, where this blade is listed on page 34. The jihada is a characteristic mix of itame and straight-grain masame-hada running close to the shinogi, animated by swirling dark lines of chikei. The hamon is the school’s signature sanbonsugi – modelled on the Seki-Kanemoto tradition but distinguished by clusters of nie crystals pooled in the valleys between the cedar-tree peaks, a hallmark of the Darani school. The boshi takes the elegant saki-Jizô form, combining a midare komi transition with a rounded tip. The blade is rated ô-wazamono for cutting ability – among the highest rankings possible – and carries the Fujishiro rank of jô-saku.

The sword comes complete with a striking Edo period uchigatana-koshirae in glossy black lacquer adorned with gold kiri-mon crests in fine maki-e – one of the most refined family crests in Japanese heraldry. The shakudô tsuba with its nanako ground and raised gold kiri-mon carries an NTHK-NPO certificate, as does the fuchi-kashira attributed to Inaba no Suke Yoshioka of the mid-Edo period. The entire set has been cared for across generations and arrives in a vintage storage box with hakogaki and sayagaki by Kanzan Satô, appraised in 1972.
