"The conscription of comfort women was a grave anti-human crime of Japanese militarism committed against Asian countries victimized during World War II," Foreign Ministry spokesperson Lu Kang told reporters, welcoming the ruling.
The US Supreme Court's decision came on Monday, despite the Japanese government's opinion presented to the court in February, after it was asked to hold hearings seeking the removal of the statue.
"The crimes of Japanese militarism are irrefutable and cannot be denied," he said.
Comfort women were women and girls forced into sexual slavery by the Japanese Army in occupied territories before and during World War II.
The statue was erected in 2013 as a tribute to more than 200,000 Asian and Dutch women who were forced into sexual slavery between 1932 and 1945.
