Kanmon Pedestrian Tunnel

**Full experience route:** Walk one direction, explore Moji Port, return by ferry (¥400, 5-min ride, every 10 min). The ferry crossing provides surface perspective of the strait you just walked beneath, creating satisfying symmetry. Total experience: Shimonoseki → tunnel walk (15 min) → Moji Port exploration (90 min, visit retro district and waterfront) → ferry return (5 min). Budget 2.5 hours. **Moji Port exploration:** The Kyushu-side exit places you in Moji Port Retro District, a preserved Meiji/Taisho (1890s–1920s) harbor area with Western-style architecture — Moji Port Station (国指定重要文化財, Important Cultural Property), former trading company buildings, and waterfront promenade. Key stops: Blue Wing Moji drawbridge (opens hourly for ship passage), Moji Port Art Museum (¥200), and retro cafes serving Moji's famous yaki-curry (baked curry rice, ¥900). The district is compact (20-min walk) and nostalgic. **Tunnel midpoint ritual:** The exact Honshu-Kyushu boundary is marked by a white line painted across the tunnel floor, midway through (390m from each entrance). Tourists photograph themselves straddling the line — one foot on Honshu, one on Kyushu. Beneath you is the Kanmon Strait seabed, 60 meters above your head is 30 meters of water and 500+ ships passing daily. It's goofy but undeniably cool. **Combine with Shimonoseki sites:** The tunnel entrance is 10-min walk from Akama Shrine and 20 min from Karato Fish Market, allowing efficient half-day combination: Karato Market (morning, 9:00–11:00) → Akama Shrine (20 min) → Kanmon Tunnel walk + Moji Port (2.5 hours) → ferry return → Hinoyama Park ropeway (sunset). Full-day Shimonoseki itinerary maximizes the city's unique strait-focused attractions.
