A Suriage katana made during the Koto period is now in stock. The Society for Preservation of Japanese Art Swords has recognized this katana as the work of Kongohyoe Moritaka, and has issued a certificate of authenticity for it as a sword of great value that should be preserved for future generations.

Moritaka was a group of craftsmen who made swords in Chikuzen Province (present Fukuoka Prefecture) from the end of the Kamakura Period to the end of the Muromachi Period. Moritaka was a swordsmith in the Shohei Period (1346-1370) of the Northern and Southern Dynasties, and is known as the founder of this school, and is also said to be Kuniyoshi's nephew. He belonged to the school called Kongohyo'e, and is therefore known as Kongohyo'e Moritaka. The Kongohyo'e were a school located near Dazaifu in Chikuzen Province, and lived on Mount Uchi. Mount Uchi had a shrine called Kongohoman, another name for Kamado Shrine, which is why they were called Kongohyo'e. Tradition has it that his sword was also Yukimura Sanada's favorite sword, and his work was favored by the warrior class.

This piece has the unique characteristics of Koto's swords, with a thin suguha hamon on the hada that is partially mixed with itame and mokume as well as masame. The boshi is turned back in the shape of an omaru, creating a very elegant yet practical atmosphere. The blade of the sword is engraved with a ryochiri hi. This sword is a suriage, and it is estimated that the original blade length may have been up to about 2 shaku 7 sun. Since this is a Kot period piece, there are a few spots of black rust, but the overall condition of preservation is very good, and the quality is such that it could become your family heirloom. The shirasaya is also very elaborate, indicating that the sword has been carefully stored for a long time. Please cherish this piece as your family heirloom.
