How to bid on Yahoo Japan Auctions?
Most Japanese sellers will not deal with bidders from outside of Japan. That's why it's helpful for you to use an intermediary service that will deal with the seller on your behalf. At this point, you can use JAUCE to place your bids in real-time and JAUCE will do the rest to ship the items to you. This way, you can enjoy Japanese online auctions from the comfort of your own home.
