12. Nightclubs in Japan have only been allowed to stay open past midnight since 2015.
In 1948, Japan adopted a law that forbids dancing after midnight in nightclubs, bars, and other public places. In the post-war years, nightclubs were places for adult entertainment. The situation has long changed but the restriction remained. In 2015, the law was revised and nightclubs and bars with appropriate lighting can now be open all night long.
