1. What is a Samurai Castle Town?
In feudal Japan, castles were not just military fortresses — they were the centers of politics, culture and urban life. A “castle town” was built around the lord’s castle and served as a comprehensive administrative and military hub. Samurai residences, merchant districts, craft areas and temples all arose in concentric patterns around the stronghold.
1-1. The Urban Layout of Power
Samurai were allotted plots called “buke-yashiki” (武家屋敷) near the castle, while merchants lived farther out. Roadways were designed with defense in mind, often winding or lined with earthen walls and canals to slow any enemy advance.
2. Samurai Housing & Urban Life
2-1. Samurai Residences
The residences of samurai were simple yet clearly structured: a gate, longhouse for retainers, main house, treasury, and garden. The layout and position of each home within the town reflected the samurai’s rank and his proximity to the lord.
2-2. Merchant vs. Warrior Districts
In a castle town, you will often clearly distinguish the samurai quarters from the merchant and artisan zones. This spatial separation reinforced the hierarchy of feudal society and still shapes the historic districts of cities such as Kanazawa and Matsumoto.
3. The Castle as Hub of Governance
Beyond defence, the castle served as the heart of administration: governmental offices, financial vaults, and living quarters all evolved around it. The grandeur and layout of the castle were symbolic of the samurai’s power and authority.
3-1. Castle Town Governance
Warriors held official posts — such as town magistrate (machibugyō) and construction overseer (fushin bugyō) — which meant the castle town functioned as a full administrative city. This system is the direct ancestor of Japan’s modern municipal governance.
