Iwakuni Castle — Hilltop Fortress Over the Valley

**Ropeway + hiking option:** The ropeway ascends from near Kintaikyo Bridge to the mountaintop station (3 min, every 15 min). From there, a 400-meter stone path winds through forest to the castle — a pleasant 10-min uphill walk past stone walls and castle gates. Alternatively, a hiking trail ascends directly from Kikko Park (40-min hike, free) through woods and past ancient stone fortifications. The hike offers solitude and exercise; the ropeway saves time and leg energy. **View from the top:** The castle's fifth-floor observation deck (actual third floor internally — the reconstruction added height) provides unobstructed 360° panorama. The Kintaikyo Bridge view confirms its architectural elegance from this aerial perspective. South views show the Seto Inland Sea islands 15km distant. The best time is late afternoon (15:00–16:00) when sun angles create depth and shadow revealing the valley's topography. Morning is backlit. **Cherry blossom timing:** Mt. Yokoyama's castle grounds host 800 cherry trees that bloom late March–early April, concurrent with the trees framing Kintaikyo Bridge below. The ropeway runs extended hours during bloom season (until 19:00) for evening viewing. The castle is illuminated during this period (until 22:00), creating dramatic nighttime silhouette. Bloom-season crowds triple normal visitor counts. **Efficiency tip:** Combine castle visit with Kintaikyo Bridge in a 3-hour circuit: Kintaikyo Bridge (45 min) → lunch at Kikko Park (30 min) → ropeway + castle (90 min). The combined ticket (¥970) saves ¥210 vs individual purchases. Start at 10:00 to avoid midday heat during summer months.
