Saga Castle History Museum — Transparent City Origin Story

**The Great Hall at dusk:** The museum closes at 18:00 but the outer castle grounds remain open. At dusk, the Great Hall illumination begins and the stone moat reflects the building — one of Saga's finest photographic compositions, utterly unknown to tourists. **Meiji figure connections:** The museum contains personal possessions of Okuma Shigenobu (founder of Waseda University) and Eto Shimpei (father of the Japanese justice system) — both Saga natives. The personal letters on display, combined with explanatory panels, make the Meiji transformation feel individual rather than abstract.
