Tin miniature toy taxi, car, vintage

A miniature tin taxi in yellow with passengers in the taxi. The taxi driver is doing good business, the taxi is full! The miniature taxi is made in Japan, this is on the back of the car with the letter T above it, in our opinion, with the N below it. What this stands for is not clear to us. The tin toy taxi is in good condition, the front mudguard is slightly crooked, see the photos.
