A Japanese court has ruled that not recognizing same-sex marriages is constitutional. It dismissed plaintiffs' claim for government compensation, saying current legal provisions cannot be ruled unconstitutional.

The Tokyo District Court handed down the ruling on Wednesday in a damages suit filed against the government by eight plaintiffs, including same-sex couples. The plaintiffs argued that provisions in the civil code and other legislation that don't recognize same-sex unions are unconstitutional.

The Tokyo District Court is set to hand down a ruling in a damages lawsuit claiming that the government's non-recognition of same-sex marriage is unconstitutional.

The eight plaintiffs argued that the inability of same-sex couples to marry disregards the principles of freedom and equality guaranteed by the Constitution. The Japanese civil code does not allow such marriages. The plaintiffs include same-sex couples living in Tokyo.

Japan's Crown Prince Akishino has said he approves of his eldest daughter Princess Mako's marriage to her college classmate which was postponed.

Crown Prince Akishino spoke to reporters ahead of his 55th birthday on Monday.
