Smartphone time limit rules have been officially introduced in the city of Toyoake, Aichi Prefecture, marking a national first. On Monday, the city assembly passed an ordinance recommending a daily cap of two hours for personal digital device use. This rule applies to smartphones, gaming consoles, and other digital gadgets used outside work or school. The new measure is scheduled to take effect on October 1. It comes amid rising public concern about the negative effects of screen overuse, especially on children and families. Although the ordinance carries no legal penalties, it nevertheless represents a formal push to curb excessive digital consumption.
Moreover, Toyoake officials emphasized the need for balance in technology use. The ordinance advises families to limit screen time and encourage healthy routines. Specifically, it recommends elementary students avoid digital devices after 9 p.m. Meanwhile, for junior high school students and older, the cutoff time is 10 p.m. Importantly, the city stressed that sufficient sleep is critical for young people’s mental and physical development. Officials tied the two-hour guideline to sleep studies and recommendations from national health authorities. Based on this, the city calculated average screen time on weekdays and concluded that longer usage could lead to sleep issues.
Furthermore, Toyoake Mayor Masafumi Kouki supported the ordinance, calling it a preventive health measure. He highlighted the role of families in enforcing digital boundaries and said the city would offer support. To assist families, Toyoake plans to create a consultation system for parents seeking advice on managing device use. While the smartphone time limit is not enforceable by law, it reflects a broader trend toward digital wellness. According to experts, screen overuse can cause sleep disruption, social isolation, and reduced family interaction.
In addition, the ordinance encourages households to create their own usage rules. It also underscores the city’s commitment to promoting responsible digital habits. As a result, Toyoake’s policy may influence other municipalities. Looking ahead, experts say more local governments could explore similar non-binding measures to support healthier lifestyles. This move signals a growing awareness in Japan of the social impact of digital media. By introducing a smartphone time limit, Toyoake is taking a proactive step toward balancing connectivity with well-being.
