Thanks. I get limited luck with public proxies. When I get through it's Sooooo SLooooow to be absurd. I guess I'm looking for a tunnel based in Japan. I want to hear from someone with good experience with one before I hand over my credit card info to some third world weasel.
Public proxies can be like that but that is the chance you take. It is even trickier when you create a proxy chain, (about the only thing I used to enjoy about IE was the ease this was done), though that is much more secure. Most proxies can handle https, some cannot (if that was what you meant by tunneling), the proxycheck link I gave you has a test for that, (test2). As far as using your credit card on the net it is always a good idea to have a credit card especially for that purpose with a low limit ($500 or less). Even if you do a lot of purchasing on the internet it is always good to have a card for cases where security may be in doubt but you wish to take the risk anyway.
Not to rant on, (occasionally I do), but Tor itself has exit nodes in Japan but it can be a bit of work configuring Tor to use just them. But Tor exit nodes offer no more real security than an https proxy and maybe a little less. A public proxies strength lies in its' rate of traffic. A slow proxy is flooded with requests and picking out yours would be very difficult indeed, (public proxies tend to fluctate in speed depending on the time of day to reflect their usage). From a security standpoint as long as it allows the https protocol that should be all you need.
