Features:\u3000In the late Muromachi period, Japan was in the midst of intense warfare between the Toyotomi and Tokugawa factions, with many battles fought using swords and tanto.
\nDuring this time, the production of tanto was active especially in Mino and Bizen, where smiths such as Sukesada and Kiyomitsu flourished.
\nHowever, after the wars ended, the demand for tanto decreased significantly.
\nIn the Edo period, formal codes were established, and samurai began to carry a matched pair of long and short swords (daisho) when appearing before the shogun.
\nMuch like today\u2019s businessmen, many daimyo and their retainers were required to serve limited terms in Edo.
\nThe country also adopted a policy of national isolation, which closed Japan off from the rest of the world.
\nThis allowed unique Japanese culture and characteristics to develop.
\nThe policy of alternate attendance (sankin-kotai) was an Edo period system enforced by the shogunate that required considerable financial expenditure.
\nIt is said that the shogunate kept a close watch on these activities to ensure there was no waste or suspicious behavior.
\nThe stability of the Edo period can be attributed to the presence of highly intelligent and capable administrators.<\/p>\n

Koshirae:
\nTsuka: Wrapped in black cord and lacquered.
\nSaya (Scabbard): Vermilion lacquered saya with black stripes.
\nKozuka: Plain copper base engraved with a landscape motif.<\/p>\n

Aoi Art\u2019s Comment:\u3000This is a robust tanto with thick kasane made by Bishu Osafune Kiyomitsu.
\nDated to a day in February, 1565 (Eiroku 8).
\nThe \u201cEiroku Incident\u201d occurred on May 19, 1565, when Ashikaga Yoshiteru, the 13th Shogun of the Muromachi shogunate, was attacked and killed at the Nijo Palace in Kyoto by the forces of Miyoshi Yoshitsugu and the Miyoshi Sanninshu (Three Miyoshi), including Matsunaga Hisahide.
\nIt is also known as the \u201cEiroku Political Incident.\u201d
\nAfter the Muromachi period and into the Edo period, tanto were no longer in practical use, and their production ceased.
\nAs a result, existing tanto are rare today and are actively sought after by collectors.<\/p>\n

Historical Context:\u3000A time of intense conflict between the Toyotomi and Tokugawa factions.<\/p>\n
