16525 Shumarinaiko (provisional designation 1991 CU2) is a stony Nysian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 14 February 1991, by Japanese astronomers Kin Endate and Kazuro Watanabe at the Kitami Observatory on the island of Hokkaidō in northern Japan.[12] The asteroid was named after the Japanese Lake Shumarinai.[2] Its sub-kilometer sized minor-planet moon was discovered in 2013.
