Japan Speed Test

TestMy's servers are located world wide, in locations where a large majority of the worlds popular websites are hosted. Despite any distance users in Japan can still accurately benchmark their connection here. If you're testing outside the US or EU or Asia you have to understand that the distance will be a factor as well as international Internet routing. If your provider has poor peering or there is a bottleneck along your route then your speed test results will suffer. Greater distances result in more chances for your connection to hit a snag along the route.

Test My Download Speed and Test My Upload Speed to compare your internet speed.

Other speed tests, especially tests offered by your Internet provider try to eliminate routing factors. This can make your connection appear faster than it really is. If you visit many websites in the North America, Europe, Australia or Asia the results returned here will be a more realistic representation of your useable connection. Truthfully, do you want to know how fast your connection is within your providers network or do you want to know how fast it is to the locations where the websites you visit are being hosted? TestMy.net is not a best case scenario connection test and will test your Internet under real world conditions. [read more]
