The strait plays a crucial role in maritime navigation, allowing ships to travel between these two significant bodies of water. This strait is also known for its historical significance, particularly during the Sino-Japanese War when the Treaty of Shimonoseki was signed in 1895. The surrounding area features beautiful landscapes and is home to various marine life, making it an important ecological zone as well.
