▪️Kashu Ietsugu
This blade is attributed to Kashu Ietsugu (加州家次), a swordsmith active during the late Muromachi period (early 16th century). The term “Kashu” (加州) refers to Kaga Province, an old regional name for what is now Ishikawa Prefecture in central Japan.
Ietsugu lived and worked in Kaga Province, crafting swords as his livelihood. At the time, the region was governed by the Maeda clan (前田家), a powerful samurai family. The Maeda originally served under the warlord Oda Nobunaga (織田信長), one of the most influential figures in Japanese history. As trusted retainers, they eventually rose to prominence in their own right.
The founder of the Maeda clan’s power was Toshiie Maeda (前田利家), a skilled warrior and political figure. Through his alliance with both Nobunaga and later Toyotomi Hideyoshi (豊臣秀吉), he became the feudal lord (daimyo) of Kaga. His domain was famously known as “Kaga Hyakuman Goku” (加賀百万石), meaning “one million koku of rice”—a measurement indicating an amount of rice sufficient to feed approximately one million people. This immense agricultural wealth made the Maeda clan one of the richest and most influential families in feudal Japan.
Thanks to this economic prosperity and political stability, Kaga became a center of culture and craftsmanship. Many skilled artisans, including swordsmiths like Ietsugu, flourished under Maeda patronage. Swords from this period and region are valued not only for their battlefield utility but also for their refined beauty and craftsmanship—symbols of both martial tradition and artistic excellence.
