Aki Sea

The Aki Sea is a maritime body of water between Honshū and Shikoku islands with depths around 105 meters (345 feet), serving as an important waterway for shipping and fishing. Multiple ports and ferry routes connect coastal towns and islands throughout Hiroshima Prefecture across these waters.

During the Edo period, these waters served as crucial trade routes connecting major economic centers across Japan. The sea enabled commerce between distant coastal regions and played a key role in the country's economic network at that time.

Fishing villages along the Aki Sea maintain ways of working that have been passed down through generations, shaping how communities live and work today. You can see these traditions reflected in the daily rhythm of the ports and settlements scattered across the coast.

Ferry services connect the ports and islands throughout the region, making it easy to explore different areas by water. Check ferry schedules before your trip to plan which communities or islands you want to visit during your time here.

This waterway is home to more than 500 aquatic species, creating a rich marine environment that many visitors overlook. The variety of life here makes it an important part of the larger Seto Inland Sea ecosystem.
