Does my brother need a power of attorney from my parents to take my 12-year-old brother to Japan?

Yes According to the information inquired by Ma Honeycomb, minors need to be accompanied by guardians when going abroad. If you are accompanied by a non-guardian, you need to entrust a notary. Article 1 6 of the Law of People's Republic of China (PRC) on the Protection of Minors, which came into effect on July12007, stipulates: "If parents are unable to perform their guardianship duties for minors due to going out to work or other reasons, they should entrust other adults with guardianship to perform them on their behalf." According to the relevant provisions of the General Principles of Civil Law, parents of minors are guardians of minors. A guardian shall perform his guardianship duties and protect the person, property and other lawful rights and interests of the ward. Minors need their parents' consent and companionship to travel abroad. If he is not accompanied by both parents or one of them, his parents should entrust others or relevant organizations to send someone to accompany him. Legally speaking, this is actually a temporary guardian appointed by parents for minor children during their travel, entrusted to supervise minor children.
