Arao Higata

Arao Higata is a mudflat covering roughly 754 hectares of shallow wetland terrain in Arao. The landscape shifts between water and exposed mud depending on the tides, creating different habitats for wildlife throughout the year.

The site gained official recognition as a Ramsar wetland in 2012, joining Japan's protected wetland network. This designation followed Japan's initial adoption of the Ramsar Convention in 1980.

Local residents engage in regular monitoring activities and participate in educational programs to maintain and study the diverse species within the mudflat ecosystem.

The location offers several observation points and walking paths for visitors to view wildlife up close. Public transportation connections from Kumamoto provide convenient access to the area.

The mudflat is known for harboring a wide variety of invertebrate creatures like worms and small crustaceans within its mud layers. These organisms form the base of the food chain and support the large bird populations that pass through.
