The number of electric kick scooter users has surged in Japan, three months after regulations for such vehicles were relaxed.

At the same time, however, traffic rule violations involving such micromobility devices have also increased sharply, with related businesses and police scrambling to address the situation.

Electric kick scooters are popular among people in their 20s or 30s. Following a road traffic law revision in July, people age at least 16 can now use the motorized standup scooters without a driver's license.
