¥298,000 ¥350,000

Proudly presenting a Shinto-period katana with an appraisal certificate bearing the signature “Monju” (Wisdom). 

The blade is in excellent overall condition, featuring an antique polish that has been freshly honed; it is free of flaws, rust, or chips. However, there is an 8mm forging mark approximately 15cm from the hamachi on the sashimoto side, and another forging mark that is beginning to form fukure approximately 24cm from the hamachi. The jigane features a striking pattern of itame mixed with mokume, making it a sight to behold. The hamon is a refined sugaha with a blurred niokuchi, giving it an elegant finish. The nakago is engraved with the character “Monju.”

While “Monju” can mean “wisdom” or refer to Manjusri Bodhisattva, here it is the pseudonym favored by Nanki Shigekuni, a court blacksmith for the Kishu Tokugawa clan during the early Edo period. Shigekuni’s lineage originally belonged to the Yamato-Tegai school of swordsmiths, but his skills were recognized by Tokugawa Ieyasu, and he became the Tokugawa family’s official swordsmith. When the Kishu Tokugawa clan was established and Tokugawa Yorinobu (the tenth son of Tokugawa Ieyasu) became the lord of the Kishu domain, Shigekuni school served as a court swordsmith and left behind many masterpieces until the end of the Edo period. Since the Tegai school in Yamato Province worshipped Manjusri Bodhisattva, the second-generation Shigekuni favored engraving the “Monju” signature; therefore, this work is also attributed to the second-generation Shigekuni.

In December 2000, the Society for the Preservation of Japanese Art Swords certified this piece as an authentic Monju work and issued a preservation certificate recognizing it as a piece of high value worthy of preservation for future generations.

We are offering this katana, crafted by a swordsmith who served the Tokugawa family and accompanied by a certificate of authenticity, at a special price. Do not miss this opportunity.
