This unusually beautiful blade was discovered in 1945 at the Isonokami-jingu Shrine in the Japanese city of Tenri. The sword is strikingly different from the edged weapons familiar to us from the Land of the Rising Sun, first of all, the complex shape of the blade - it has six bizarre branches, and the seventh, obviously, was the tip of the blade - therefore the weapon found was named Nanatsusaya-no-tachi (in. with Japanese - "Seven-toothed sword").
The sword was stored in terrible conditions (which is very unusual for the Japanese), so its condition leaves much to be desired. There is an inscription on the blade, according to which the ruler of Korea presented this weapon to one of the Chinese emperors. A description of the exact same blade is found in Nihon shoki, the oldest work on Japanese history: according to legend, the seven-toothed sword was presented as a gift to the semi-mythical empress Jingu.
Having carefully studied the sword, experts came to the conclusion that, most likely, this is the same legendary artifact, since the estimated time of its creation coincides with the events described in Nihon shoki, in addition, it also mentions the Isonokami-jingu shrine, so the relic just lay there. there for more than 1.5 thousand years, until they found it.
