I have purchased something off there before and by the end of the transaction it is not that cheap with all the extra fees etc (came to about double what auction item was for), I had a mate who used to live in japan do it all for me as on some of the payment screens google/chrome didn't translate very well. It is possible but I would only use it if its something that you just can't get anywhere else? People on here may know of different ways around this but I can only speak from my experience.
