Good question. I asked myself the samething when i noticed that Google registered the domain name Mirasearch.com.
I guess it has something todo with future…. Now that is an educated guess at best. Wiki says : Mirai (未来) is a Japanese word meaning “the future” and may refer to: People, Fiction, Food, Technology, Text. The Big Q is why did big G register miraisearch.com ?
New search engine ? New technology ? New Whatever ?
Here’s the WHOIS output :
