Here are few vans our customers have imported recently. Get an idea for the price and models you can get in Japan.
And here is a secrete or a loophole on how to import one for a very good price.
Choose Toyota Hiace Welcab! It's a Hiace for people with special needs, have off rump and other equipment inside. But they cost much less than regular Hiace. $3000 to $5000 less! Also, they are coming with a much tidier interior. When the van arrives in the country, compliance will remove all speciality equipment and comply it as a regular Hiace. Good if you don't need seats at the back, and going to use it as a tradesman van. Or you are going to convert it to a Camper van.
Need a regular van - they also sell for less than anywhere.
After a 15 seater commuper or even a 40 seater Toyota Coaster - all available at Japanese Car Auctions.
