Japan has decided, for the first time since the Meiji Restoration, to finally lower the legal age of majority (adulthood) to 18, effective April 1, 2022. But before anyone starts celebrating, note that the drinking age, smoking age, and gambling age will all still remain at 20, because reasons. Really. Despite the fact that the age limit will now be 18 for literally ALL other adult rights and responsibilities, including, but not limited to, being tried and punished as an adult.
So for 18-19 year old young adults, this feels like a cruel April Fool's Day joke at best.
