What's your favorite old school Japanese car?

Spent my summers growing up driving around Northern New Jersey with my Dad doing estimates for his gutter business...became very fond of his 72 Datsun pick up. Think it was a 620 if I remember right. Little truck took a beating over the years. Was the first vehicle I did a motor r&r on by myself...think I was 9 or 10.
Dad taught me how to drive in it. He let me drive on the roads when I was 9. All was going well....until I rolled up at a traffic light...next to my mother...
