We don’t have many MUP’s in Tokyo or Japan, but any e-bike which can move without pedaling must have a license plate, and is not allowed on a MUP. These bikes are all over Tokyo, and the police are clamping down hard on them, citing them for not having license plates, and citing riders for not wearing proper motorcycle helmets and/or operating a motor vehicle without a license. Getting a plate is not at all hard, but a drivers license in Japan costs a lot of time and money to get.
