Normal result

IP address uses IP addresses which are currently shared with 1 other domain. The more sites share the same stack of IP addresses, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise can be misinterpreted by Google and other search engines. Our service has detected that Japanese is used on the page, and it matches the claimed language. Our system also found out that main page’s claimed encoding is shift_jis. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

It lies approximately 6220 miles away from the server location (United States) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to Japan or just closer to the user base.
