Kanmon Straits
関門海峡
Water scenery — lakes, gorges and falls that reset the pace of a trip.
What this place is
The Kanmon Straits (関門海峡, Kanmon-kaikyō) or the Straits of Shimonoseki is the stretch of water separating Honshu and Kyushu, two of Japan's four main islands. On the Honshu side of the strait is Shimonoseki (下関, which contributed "Kan" (関) to the name of the strait) and on the Kyushu side is Kitakyushu, whose former city and present ward, Moji (門司), gave the strait its "mon" (門). The straits silt up at the rate of about 15 centimetres per annum, and dredging has made it possible to build the Kitakyushu Airport at low cost. Western maps from the 19th century also refer to this waterway as the Straits of Van der Capellen.

Why it is worth the trip
- Clear water that changes colour with the light, from deep blue in summer to jade after rain.
- Walkways, bridges and viewpoints built right along the water so the scenery unfolds as you move.
- Reflections of surrounding peaks and forest on calm mornings — the classic postcard shot.
What you can do here
- Walk the riverside or lakeshore promenade; most routes are flat and clearly signposted.
- Take a sightseeing boat or rent a rowboat, canoe or SUP where the water is calm.
- Photograph at golden hour, when low light makes the surface glow and crowds have thinned.
- Stop at a lookout café or rest house for local sweets with a water view.

Getting there by public transport
Good to know before you go
- Paths near falls stay wet and slippery — wear shoes with grip, not sandals.
- Water volume peaks after rain and during snowmelt; the falls are far more dramatic then.
- Boat services shrink or stop in winter, so check the seasonal timetable before travelling.
