I found a 1968, Japanese documentary on railways on youtube. And spotted some very cool kei cars. Like the Mitsubishi Minicab and Honda T360 above.
Another closer view of that Mitsubishi.
A Daihatsu Fellow smokes away.
A Volkswagen in Tokyo. Maybe the only place where one of these was a rare sight in 1968.
A Subaru 360 Custom (station wagon). Running clean - no doubt fitted with Subaru’s automatic oil injection.
