If you know the name of the server that you belong to, you can probably try using something like [downforeveryoneorjustme.com this site] and paste the IP address for the server that you belong to see if it is up or not.

If the site reports it is just you then you can show that to your ISP and says that you have difficulties reaching Japanese websites and provide them the IP address. They cannot ping the IP address, neither can you so they need to do something like layer four traceroute (lft) from their end to see if a host is up. Other way would be stuff like "banner grabbing" or really just abusing telnet to make it talk to the HTTPd server.

In short you pretty much need to somehow escalate the issue with your ISP because all their level 1 tech staff would most definitely read simple scripts and presumes your router or your setup is at fault.
