SEO for targeting English Speakers in Japan
A common misconception is that if you are targeting English speakers on your website, the only language you require is English… Not entirely. Here is a big reason to have a bilingual website in both Japanese and English.
Localization or the Location and or Language of the location you target matters — to the search engines.
As you may know, the search engines such as Google and Yahoo favor the web pages closer to the location where the search user is, and the web pages in the language spoken where the search user is. This is true even if the keyword is written in English. To put it bluntly you should be considering having both languages on your site even though your only business comes from English speakers in Japan because more often than not their results will be effected by their location. Localize your website in Japanese and you will have better results for your English keywords for Search Engines in Japan.
