Japan lowers age of adulthood to 18

My students in my high level lesson studied how Japan's government has lowered the age at which people become adults. It is the first time since 1876 that this has happened. From the year 2022, teenagers will become adults at the age of 18, which is two years earlier than the age at which adulthood currently legally happens. However, even though the age has been lowered, there are still certain things that will not change. The legal age for drinking alcohol, smoking and gambling will remain fixed at 20.
