関門海峡
The (Asian Highway Network ) is a suspension bridge crossing the Kanmon Straits, a stretch of water separating two of Japan's four main islands. On the Honshū side of the bridge is Shimonoseki (, which contributed "Kan" to the name of the strait) and on the Kyūshū side is Kitakyushu, whose former city and present ward, Moji (), gave the strait its "mon".
