Yagyū Shinkage-ryū: 柳生新陰流 - The Divine Shadow School

Yagyū Shinkage-ryū is one of Japan's most historically significant and influential classical swordsmanship traditions. Here's an overview of this distinguished martial school:

Origins and Development

• Developed from Shinkage-ryū, which was founded by Kamiizumi Nobutsuna (1508-1577)
• Established as Yagyū Shinkage-ryū when Kamiizumi passed the tradition to Yagyū Muneyoshi (1529-1606)
• The name combines "Yagyū" (the family name) with "Shinkage" (Divine Shadow)
• Became especially prominent when Yagyū Munenori (1571-1646), Muneyoshi's son, became the official sword instructor to the Tokugawa shoguns
• Maintained high status throughout the Edo period (1603-1868)
