I am currently living in Japan. I am originally from America, but after graduating from college I decided that I wanted to get some work experience in Japan. I live in Toyota city...
... but I drive a Mitsubishi. It is what is classified as a kei car. Basically that means that it is lightweight, and has a 660 CC engine. It is a Minica, and it supposedly should be getting around 22.5 km/l. That works out to 53 MPG. Not too shabby... until you consider that the Japanese government testing for fuel consumption is worse than the US method. I get around 18-20 km/l depending on driving conditions. This is purely city driving with lots of stop and go traffic. I start working in a new area from the beginning of next week, so things could change drastically!
Oh, my company got the car for me, so I can't complain too much. They cost about $4000 (USD) brand new. I can't imagine that there is a more basic car than this bad boy.
Welcome Erdrick! I also drive a Kei car! I have a 1991 Honda Beat. I know what you mean about the "claimed" mileage. Honda claims (on the infamous 10 mode) that I should be getting around 63 mpg! I typically get around 40.
Start a garage entry and get some pictures up of your Mitsu!
I cant wait to hear about your driving experiences from Japan. Often we refer to the "small cars from Japan", it will be nice to have your opinion on them as well.
