The waters surrounding the Itsuwa district are home to a resident population of approximately 300 dolphins, a phenomenon supported by the nutrient-rich currents of the Hayasaki Strait. This area has long served as a vital ecological corridor, where the proximity of the mountains to the sea creates a unique underwater topography. Unlike migratory pods, these dolphins remain in the local waters year-round, which has fostered a remarkably calm and non-confrontational relationship between the marine life and local vessels. The tradition of the sea in Amakusa is deeply intertwined with this coexistence, as the dolphins have been a constant presence for generations of local fishing communities.
The experience is defined by the understated beauty of the Amakusa Five Bridges and the rugged coastline that characterizes the region. The dolphins frequently approach the boats with a sense of curiosity, allowing for close-range observation of their social behaviors and pod dynamics without the need for artificial lures. While the cruises are available throughout the year, the clear light of the spring and autumn months often provides the most striking views of the animals against the blue expanse of the Ariake Sea. This encounter emphasizes the authenticity of the natural world and the quiet dignity of a maritime culture that prioritizes environmental respect. It remains a significant highlight for travelers seeking a genuine connection to the diverse marine heritage of Southern Japan. |
