Since this rental scooter is 125cc, a Japanese standard driver's license alone is not sufficient to ride it. (Mopeds that can be ridden with a Japanese standard driver's license are 125cc or less and have a maximum output of 4.0kW or less.) The staff suggested that since I couldn't ride the scooter with my standard license, I could switch to a car or an electric scooter that doesn't require a license, so I chose the electric scooter. The electric scooter had a higher daily rental fee, so I paid the difference. The electric scooter doesn't go faster than 25km/h, so in a way, it might be safer. They also lend out helmets (though the size was big...). The staff were very helpful, using a translation app to explain various things. It's also convenient that I can return it at Kinmen Airport.
