Powerful clans or generals from the disturbance period of Waring States Period to the Azuchi Momoyama state required the rich, massive volume and thick in kasane with high shinogi-ridge, with well-proportioned deep curve.
The latter half of Medieval Muromachi period, starting with The Onin War (応仁の乱 Onin no Ran) / (1467-77), the length and style of Japanese swords had changed - Eisho-Daiei(1504-27) it was generally 2.0 - 2.1 shaku(60-63cm) which was suitable for one-hand grip, Kyoroku-Tenbun(1528-40) it had become a bit longer to 2.2 shaku(66cm), then Ganki-Tenso(1570-91) it became further longer to 2.3 shaku or even more(70cm) and Nakago(tang) became getting longer accordingly which was designed in the style of both hands grip.
