I did it through
The cheapest I found.
Before I tried to contact a japanese on ebay and he asked me 40069.5 JPY for the pairs of denim which retails at 18900 yen
Then I tried bid-service.jp and he asked me 29408.47 JPY for the same denim.
And finally I contacted Rare-s.com who told me to pay 26109.5.
I choose this one because of cheapness of course. But bid-service.jp was really kind and quick. (Rare-s too)
I hope this guy is legit and that he will send it to me ^^
I don't worry.. he's on ebay, on yahoo auction with many positive feedback.
Hope this will help you guys to get some japanese stuff !
