Following political turmoil that rocked the Diet over the past week, ruling block Upper House members finally enacted the contentious state secrets bill late Friday night.

Earlier in the day, opposition parties intensified their protests in vain over a law that's being criticizing for not creating an independent oversight body capable of preventing the government from hiding inconvenient information at its discretion.

To enact the law, the Liberal Democratic Party-New Komeito ruling coalition on Friday extended the Diet session by two days to secure more time for deliberation and procedures to set up a plenary vote.
