Toyoake, in Japan`s Aichi Prefecture, is weighing a draft ordinance to restrict residents` smartphone, tablet and computer use to two hours a day outside work and school. The non-binding proposal also suggests children stop using devices by 9 pm in elementary school and 10 pm in middle school or older.

Mayor Masafumi Koki said the plan carries no penalties and is intended to raise awareness of the health risks of excessive screen time. A national survey earlier this year found Japanese youth spend an average of five hours a day on devices during the week.
