Lake Kameyama

Lake Kameyama is an artificial reservoir located in Kimitsu City, Chiba Prefecture, created by the construction of the Kameyama Dam on the upstream section of the Obitsu River. The dam was built between 1969 and 1980 as a concrete gravity dam designed primarily for flood control and water supply. The dam's catchment area spans 69.7 square kilometers and can store 14.75 million cubic meters of water, impounding approximately 139 hectares of land when full.

Lake Kameyama holds the distinction of being the largest and only dam lake in Chiba Prefecture. The lake has formed a complex and winding shape through a beautiful ravine, creating a scenic waterway that has become a significant recreational destination in the region. The lake showcases scenic beauty across all four seasons, making it particularly attractive to visitors seeking natural landscapes within easy reach of Tokyo.

The lake serves as a popular destination for outdoor activities and seasonal tourism. Fishing enthusiasts frequent the area, as it has gained recognition as a prime bass fishing spot around Tokyo, with numerous rental boat shops and fishing gear stores available. Visitors can enjoy hiking trails, boat rides, and seasonal festivals, with the Kameyama Autumn Festival being particularly notable for its scarlet maple leaf viewing opportunities from tour boats. The area also features abundant hot spring inns and camping facilities for those seeking extended stays.

Lake Kameyama is accessible via a 15-minute walk from Kazusa-Kameyama Station. The lake can be clearly observed from the road above the Kameyama Dam, and walking trails provide various vantage points for visitors. The dam is located at 33 Toyoda, Kimitsu 292-0523, Chiba Prefecture. Access to the lake and surrounding recreational areas is generally free, though specific activities such as boat rentals and guided tours may require separate fees. The location's proximity to the Tokyo metropolitan area makes it an accessible day-trip destination for urban visitors seeking natural scenery and outdoor recreation.
