They are not tour vans, but vans of the pop singer Hamasaki Ayumi.
You should see what they do for car shows, you would think you just walked into the an anime set in the future.
To the ppl who says that the vans are overdone, this is really considered mild, when it comes to customizing ones rides the Japanese go all out, so for some of you, you might say rice or fugly or too much... but to them.... its unquie, individual, and still not done.
when it comes to moding cars the japanese have it going on, they are very creative and dont bitch about the price of a hood or trunk or springs
