Historical Background: Echizen Rai is another name for Chiyozuru Kuniyasu of Echizen Fuchu, regarded as the founder of the Chiyozuru school, whose lineage traces back to Yamashiro.
\nDuring the Nanbokucho period, around the Joji era (1362\u20131368), Nitta Yoshisada (1301\u20131338) was a military commander active from the late Kamakura to Nanbokucho period.
\nIn 1333, he attacked Kamakura and overthrew the shogunate, playing a key role in establishing Emperor Go-Daigo\u2019s Kenmu Restoration.
\nHe later opposed Ashikaga Takauji and fought in the Hokuriku region as a leading supporter of the Southern Court (Emperor Go-Daigo\u2019s side), but was killed in battle at Fujishima in Echizen in 1338.
\nThis is a well-made and enjoyable sword, and the koshirae is also of respectable quality.<\/p>\n
