Sayama pond is a 7th century pond located in Osakasayama city, Japan. The chronological survey of potteries near the lake confirmed that the pond was completed in 7th century.

The pond was declared a historic monument in 1946 and is listed as World Heritage Irrigation Structure by International Commission of Irrigation and Drainage. With a perimeter of 3.4 km and area of 40 ha, it is the largest pond in Osakayama city. The pond has been used as a reservoir for irrigation. The pond is surrounded by a park and has Sayama-ike Museum nearby. Over 50 species of wild birds have been spotted in the pond area. [2][3]
