The red circle above indicate the time we discuss in this section
After the Onin-no-Ran, Kyoto was in a devastating condition. Distinguished swordsmiths in the Kyoto area were almost all gone. Sengoku Daimyo (warlord or feudal lord) needed a large number of swords from nearby. Mino and Bizen areas were the active sword-making places during the Sengoku time. It was because the Mino province was located in a convenient location from many feudal lords. Also, the Shizu Group from Yamato Den (school) moved to Mino province. Tegai Kaneyoshi from Yamato Den moved to Mino, and many swordsmiths from Yamashiro and Yamato areas moved to Mino. Thus, Mino could supply the high demand for a large number of swords. During this wartime, Samurai demanded a very practical sword that wouldn’t bend or break but cut well. Together with swordsmiths in the Mino area, Bizen Osafune swordsmiths fulfilled the high demand also
Kazu-Uchi-Mono and Chumon-Uchi
- Kazu-uchi-mono was a sword made just good enough for one battle. They were not made for permanent preservation.
- Chumon-uchi was a custom-made sword. Good shape, good forging, often engraved the swordsmith’s name and the name of a person who ordered it.
Characteristics of Mino-Den Swords
