It might be the fastest means to cross Kanmon strait. Took us five minutes from Karato to Mojiko. The pier is in between Karato market and Kaikyokan aquarium and tickets can be purchased right next to the Family mart outside Kaikyokan.

This 5-minite-boat-ride between Karato(Shimonoseki) and Mojiko(Kitakyushu) is the best way to visit both sides of the Kanmon Strait. You pay 400 yen for one way or 900 yen for One Day Pass which includes the visit of Ganryu-jima Island where the famous duel was fought...More

The straits side walk is scenic. The nearby karato seafood market is good. After the brunch, do some exercise and walk. Opposite to this place is the kanmon human tunnel through which you can walk to Mojiko
