High school, year 2 (高校2年)

The second year of high school is when the 文系/理系 (humanities or science) split takes effect, and the year to learn how university entry works before the final year's deadlines. For the child it is often the busiest year for clubs and school events, and the last full year before they become a legal adult.

Age 16–17

What school expects this year

Body and mind this year

Friends, rules and screens

  • Turning 18 in high school: contracts, parental authority, voting, and what stays at 20

    18歳で成年に(契約・親権・選挙権と20歳のまま変わらないこと)

    Next year your child becomes a legal adult: a contract they sign will no longer need your consent, and you will no longer be able to cancel it for them.

    At home: Your child mentions signing up for something, a phone plan, a gym or a course, without telling you first.

    Ask the teacher: Does the school teach contracts and consumer rights before students become legal adults?

  • Phones, games and social media by age: what the national survey shows and what schools allow

    年齢別のスマホ・ゲーム・SNS(青少年のインターネット利用環境実態調査と学校の持込みルール)

    With adulthood close, contracts, in-app payments and online side jobs are the new risks, and what a minor can still cancel an adult cannot.

    At home: Your child talks about easy money online, or a side job found on social media.
