Japan’s major opposition parties submitted a bill Monday calling for same-sex marriage in the world’s third-biggest economy, a move that comes weeks after Taiwan became the first place in Asia to legalize gay marriage. The bill is unlikely to go far in parliament, where the conservative ruling Liberal Democratic Party has barely budged to advance civil rights for LGBT people — even though business leaders have demanded change, saying current policies are hurting their ability to attract top global talent. The bill from the Constitutional Democratic Party, Japanese Communist Party and others states that marriage will be established on the basis of marriage equality. Neutral language will be adopted with the terms “party of marriage” used in place of “husband” and “wife,” while “father and mother” will be replaced by “parent.”
