Tonegawa estuary has a large reed beds dotted with fallow fields and ponds, as well as golf courses. Near the estuary weir, the main stream of the Tonegawa, the Hitachigawa and the Kurobegawa rivers meet. We can see a large tidal flat around Tone Kamomeohashi bridge at low tide. This area is the habitat of some kinds of aquatic invertebrates like sandworms and shellfishes. Its vegetation is characterized by coast plants including Pinus thunbergii, Machilus tunbergii, Pittosporum tobira and Rose rugosa.
