Aso Bay

This is a peaceful bay surrounded by the Rias coast in the center of Tsushima. Ideal as an outdoor area to enjoy sea kayaking and Stand up paddle boards. Guided sea kayaking tours take you to uninhabited islands, and you can also dine on the uninhabited islands. You can also enjoy a tour on the local small cruise ship.

Pearl farming and bluefin tuna are also farmed here. Attempting to swim across to one of the uninhabited islands is reckless.
