I am not in Japan. How do I purchase web hosting from a website that sells only to people residing in Japan?
If you want a website with an IP address/physical location in Japan, then it might actually be easier to use a global/US company that has datacenters in Japan, like Amazon AWS, then you skip all the hassle and expensive of dealing with a Japanese company. If you can read/speak Japanese then maybe value-server.com is a good option. Or do you want to exactly “web hosting from a website that sells only to people residing in Japan”? In which case you probably need a Japanese speaking friend based in Japan.
