While also not specifically what you are looking into, I imported mine to Canada from Japan through a broker, and here's how my process went. I'm currently avoiding doing any actual work at work today, which should explain why I'm going into such detail.
All these prices are CAD circa 2016 for a 1995 HDJ81 with 120,000kms.
Broker - $1000
Shipping - $2634
Customs - $2016
Vehicle - $1,014,000 Yen / $12k or so, depending on current exchange
OPI (not counting parts) - $250
Registration - $85
Total - $18,000-ish.
Extra stuff (fuel, fluids, birfs, wheels, tires, rotors/pads, stereo) - $4-5k.
There was a $1000 broker fee at the beginning to a company here in Edmonton called JDM Connection. This covered his costs in arranging all paperwork relating to shipping and customs, as well as helping with the searching process, and having contacts on site in Japan to do the purchasing on site. I would browse the auction listings on the Japanese sites daily, and if I saw a vehicle that I was interested in, I would let him know. He would provide a rough translation of the inspection sheet, have a guy on site look at the vehicle in person and then tell me what kind of obvious things he noticed when doing a quick visual inspection, if it was smoked in, if something looked like it was leaking, etc. They would tell me that information, and if I was interested I would give him a maximum bid amount. That happened a couple times until I noticed what vehicles were floating through the system with absurd reserve prices, and then I won the bid on a vehicle.
I then paid the auction house for the vehicle using a wire transfer. There was a small commission on that service that the wire transfer company builds into their exchange rate.
Shipping costs were $2634 for the use of a roll on roll off ship. That was kind of fun because there are actually ship tracking websites so once they give you the name of the ship, you can see exactly where it is and watch the ship stop at a bunch of different ports on the way to Vancouver in my case. Since my truck was lifted already, shipping costs were significantly higher than they would have been for a smaller vehicle, and the weight of a Cruiser doesn't help anything. Cars are usually in the $1000-$1200 range.
Customs/Duty/GST/Border Fees/Whateverelsetheychargedmefor was a big one here in Canada, came to $2016.
At this point the vehicle was mine. I used my Aeroplan miles to get a one way first class ticket to Vancouver, that would normally be $300 or so. Got a $40 taxi ride to the port from the airport. Marvelled at the largest parking lot I've ever seen. Bought 3 tanks of fuel on the way home, worth around $200.
Out of province inspection required that I replace rear shocks (leaking), rear brake calipers (small leak), replace suspension bushing ($60), and I had to redo the birfs ($400 I think). My headlights were already DOT approved, I just modified the projectors to make the beam pattern shine the right way, otherwise they would need to be replaced.
Then, I did some extra work before getting it on the road. but it wasn't totally necessary.
Couple of things of note:
-Don't buy around the end of May. That's Golden Week in Japan and nobody works, so that adds about 2 weeks to the moving of a vehicle there.
-Pick your vehicle up yourself and drive it home. It makes for a fun adventure.
-Spend a month or two watching auction sites. If you see the same vehicle pop up multiple times, or be sold and show up again, it's got a crazy reserve price and will be floating through the system for a long time moving from auction house to auction house. Don't even bother with those ones.
-Don't remove any Japanese stickers. I hate putting stickers or decals on my vehicles, but the Japanese ones are kooky and fun to leave.
-If you are driving it home, bring a stereo. The Japanese ones won't play our radio stations here. Mine luckily had a hard drive in it loaded with music, so I spent a 13 hour drive listening to J-Pop.
