The Aoe school arose in Bitchu Province, a region celebrated for iron production since antiquity. The early eleventh-century miscellany Shin Sarugaku-ki already lists "the swords of Bitchu" among the noted products of the provinces, and roughly two centuries later the Aoe swordsmiths emerged as heirs to that high reputation, flourishing chiefly in the lower basin of the Takahashi River in such locales as Koji and Manju.

A blade designated by the Japanese government for its high artistic and historical value, a standing comparable to an Important Sword. The designation carries an export restriction: a Jūyō Bijutsuhin is kept within Japan and forfeits its status if it ever leaves the country.
The Important Art Object (Jūyō Bijutsuhin) designation dates to the 1933 Law for the Preservation of Important Works of Fine Arts, passed during the Great Depression to stem the outflow of Japan’s cultural treasures abroad. The systems of Important Cultural Property and National Treasure did not yet cover privately-held works, so accreditation by the Minister of Education marked an object as a quasi-National Treasure that could not be exported. About 8,300 works were accredited before the system closed, roughly 1,000 of them swords. The 1950 Law for the Protection of Cultural Properties superseded it: higher-ranked pieces were promoted to Important Cultural Property, the rest kept their standing Jūyō Bijutsuhin status, and no new designations have been made since.
