The Ariake Sea’s enormous tidal flats, exposed for kilometres at low tide, are home to one of Japan’s most endearing creatures: the mudskipper (mutsugoro), an amphibious fish that crawls, hops and skips across the wet mud on its fins, propping itself up and even leaping to defend its territory. Found in few other places in Japan, these comical, bug-eyed fish are a beloved symbol of Saga’s Ariake coast. Along the shore you can watch them and other mudflat life — crabs, shellfish and birds — in their unique tidal habitat, sometimes from viewing spots or on guided walks and tidal-flat experiences. Uniquely, the mudskipper is also eaten here as a regional delicacy, grilled and glazed like eel (kabayaki). Quirky and full of local character, the mudflats offer a taste of one of Japan’s most unusual ecosystems.

Tips

Come at low tide, when the mudflats are exposed and the mudskippers are active, and check tide times before you go as the flats flood at high tide. Bring binoculars to watch the mudskippers and birds, be adventurous and try the local kabayaki-grilled mudskipper if you’re curious, and combine it with the Ariake coast and the famous Gatalympics mud games.
