Hi Dotanbatan
here is some what I hope is some helpful info when considering what to buy (apologies if you already know this):
1) Parking- you need a registered parking space before you can but a car (must be within 2km of your residence)
2) WEIGHT TAX is based on engine size (the above mentioned k-jidosha runs from 4-8,000 per year depending on if it is a commercial vehicle - seats in back have less leg room- or non commercial, but that tax has just increased) Roughly speaking a "normal car" (futsusha) (with a 5 number plate) goes up to about 40,00 in tax per year - up to 2000cc. Above that it increase about 10,000 to around 3 L, and then jumps to 60 about 3 (have not had a bigger engine than a 3.2) They will also hit you for 10,000 if your car is longer than 5. m (which is why J cars are 4.9 something all the time)
3) SHAKEN (mandatory inspection that includes the minimum PL&PD) is every 2 years (shops usually charge about 60-70,000 for a K car, and 80-90,000 for a regular car (and more with add ons that they try and get you to do that are not required for the inspection- you can bring it in yourself and it is a bit cheaper but IMO not worth wasting the time.
4) INSURANCE- depends very much on your car (most companies will consider you a fairly new driver so you will probably be looking at 60,000 or more per year (again depends on your car a lot) Japanese cars are cheaper.
5) USED car- Caveat emptor, Caveat emptor, Caveat emptor, Caveat emptor
That being said, it is worthwhile buying a dealer guaranteed car (or looking at some of the big used shops that offer warrantees) such as BIG MOTORS
Cars are generally cheaper than AUS but running costs are high (parking ticket is 15,000 plus 2 points)
Parking in high cities in "shopping or other attraction areas is usually around \1,000 per hour.
In general, I would go with a Japanese car, not too old. even if it is in good condition, hoses, bushings any rubber stuff goes quicker here. 60,000 KM is about the magic number where the price plummets (which is ridiculously low by Canadian and I assume AUS standards) but be aware that 60,000 km is ALL city for the m,pst part, and used car dealers have been known to tamper with odometersツ… There is very little in the way of consumer protection for used cars. You were very much at the mercy of your dealer/shop.
Another option is to look for a shakendai car (basically the price of the inspection) and you get an older car, but you can get a pretty good, solid 10 year old car for next to nothing. I did that for a while. Foreign cars, are generally a pain in the butt- and you pay for them through the nose (though that is changing). Japanese dealers have in general good after service and IMO, if you do not want to hassle with a used car, buying a dealer used car is a good way to go- I would do that or go for a 200,000-300,000 yen car from a local shop and "hope for the best- and then in 2 years when the inspection is up, you can either extend it if it is working well or know what kind of car you really want.
Here is a search (up to 300,000) for a mazda (they do not hold their resale as well as the big 3, so they make a sweet deal for used cars - honda is the worst - or best - in hold value, so I would not buy one used)
