Japan's stance on underage drinking is unambiguous - it is strictly prohibited.

The legal drinking age in Japan is 20 years old, and violating this law can come with serious consequences.

The country's cultural norms and social customs place a strong emphasis on responsible alcohol consumption, making underage drinking a significant taboo.

Purchasing alcohol as a minor in Japan is a criminal offense.

Retail stores, bars, and restaurants are required by law to verify the age of customers before any alcohol sales.

Attempting to use a fake ID or misrepresenting one's age can result in fines and even jail time for the minor, as well as potential penalties for the business that makes the sale. - https://japanfocusguide.com/blog/can-you-buy-alcohol-as-minor-japan/?unique_id_0va1tq0h
