The copies of the Koryū Kagemitsu
The Koryū Kagemitsu is a tachi by Kagemitsu of 1322 that, even shortened, measures 80.6 cm. According to Sesko, Munetsugu copied it twice: in 1847, as it must have been before the shortening, and in 1862, just as it was then. For Sesko, the second copy is so faithful that Munetsugu must have had the original in his hands.
In the lists and the treatises
He does not appear in Tomita Kiyama’s list of shintō smiths (1933; published in 1935), according to the translation in the Japanese Sword Index. No work of his is recorded as a National Treasure, Important Cultural Property or Important Art Object in the sources consulted.
