Special feature:Ho-syu Takada Yukinaga was working at early Keicyo to
Kanbun era. Generally early Edo period, Takada school made pretty nice swords.
Neighbor country Hizen, Nabeshima Daimyo tried to export Japanese swords and potter’s ware to other places
and also imported Portuguese iron from Portugal and prohibit to use other places.
Probably Hizen sword makers made swords with this iron for making sword.
so I have never seen the sword with Nanban tetsu on the nakago.
Also the Iigane is big different from Takada and Hizen-to.
But Hamon is sometimes very similar Hizen and Takada.

From Aoi Art : This yukinaga is marvelous fine Jigane which was made at Keicyo era.
Hamon is well reserch and made almost as same as Hizen sword,
Tadahiro, Tadakuni, and first generation Tadayoshi.
First stage, Takada school made high ranking swords but later on,
gradually Takada school’s swords are not welcomed by sword demanded samurai.
