Japanese cities introduce hourly smartphone usage limits

In the city of Toyoake, Aichi Prefecture, Japan, a new initiative has been implemented to limit the amount of time residents use smartphones and laptops. This was reported by Time magazine.

The decision was proposed by Mayor Masafumi Koki, with the aim of strengthening face-to-face communication among people and promoting healthy sleep habits.

According to the recommendation, citizens are advised not to use smartphones or tablets for more than two hours a day outside of work or study. This restriction is not mandatory — it encourages self-control and a healthy lifestyle.

The mayor noted that in recent years, screen addiction has weakened human interaction:
“Even on trains, people no longer look at each other — everyone is ‘talking’ to their phones,” he said.

Experts supported this view, noting that prolonged screen time reduces melatonin production, negatively affecting sleep quality, productivity, and mental health. Moreover, excessive social media use increases anxiety and isolation.

The adopted document recommends that elementary school students stop using phones after 9 p.m., and middle and high school students after 10 p.m. The decision was approved by the local council with 12 votes in favor and 7 against.

City residents reacted differently: some found it beneficial for health and communication, while others considered it “excessive and impractical.”

At the same time, Mayor Koki emphasized that “the most important thing is bringing this topic to public discussion,” calling the initiative a step toward positive social change.

Experts suggest integrating the idea with educational programs, psychological support, and stronger family communication. The city of Toyoake is currently observing the results — the project is seen as an attempt to find a balance between digital life and real human interaction.
