unique Hamon of Ichimonji.
Special feature: The 2 greatest flows of Bizen swords in the Kamakura period are
Ichimonji school and Osafune school. Ichimonji school prospered in Fukuoka, Yoshioka
and Iwato from the Kamakura period to the Nambokucho period. This school is called
“Ichimonji” because they engrave the character 一”Ichi”(one). There are some patterns of
signature: only “Ichi”, “Ichi” with each swordsmith’s name, and just swordsmith’s name.
Yoshioka Ichimonji school occured right after Fukuoka Ichimonji in the late Kamakura
period. Famous swordsmiths are: Sukemitsu, Sukeshige, and Sukeyoshi. They made not
only similar swords to Fukuoka Ichimonji, but also Gunomemidare works. This Tachi is
quite similar to Fukuoka Ichimonji: small patterns and calm Midareba with Ko-Choji, Ko-
Gunome, and Ko-Notare. There are variety of changes and functionings in Ha, like
Sunagashi and Kinsuji. Ichi character is very clear and it shows strong characteristics of
Yoshioka Ichimonji signature. This had to be preserved very carefully.
From Aoi Art: Nakago is almost Ubu-Nakago. Mei is extremely well-engraved with
condition from those days when it was made. Sori is deep and the shape is typical
Kamakura-period shape. It is very interesting to imagine who owned this sword. We truly
recommend this wonderful Juyo Token.
