TOKYO (Reuters) - Japan's largest opposition group unveiled a campaign platform on Wednesday that said it would stand for rights like supporting same-sex marriage and different surnames for couples, marking out differences with the conservative ruling party.

The Constitutional Democratic Party of Japan (CDPJ), led by Yukio Edano, is facing a critical test in the Oct 31 general election, the first it is contesting since its formation last year, hoping to make a dent in the ruling party coalition that holds a clear majority in parliament.
