Takeda Shingen's Home — Not a Castle, But His World
Tsutsujigasaki was Takeda Shingen's primary residence and administrative headquarters for his entire career as lord of Kai Province. It was emphatically not a fortress — Shingen's philosophy was that 'people are castles, people are stone walls, people are moats' (人は城、人は石垣、人は堀), meaning he trusted loyal retainers rather than fortifications for protection. The residence reflects this worldview: a large administrative compound without the towering stone walls or keeps of a military castle.
