who calls me from +81363612930?

It was a call from Japan, because +81 is indeed Japan's country code. How many times that person called you? If he or she only did once or twice, I think you don't need to think about it (people sometimes dial the wrong number). Plus, I think it is not wise to post the whole telephone number (privacy reason). If you think it is necessary, just put +813xxx or something like that.

I searched , and i think it is a number from Japan . And it is a very famous number and many get missed calls from it . Don't know what is this number for and whose is this number ?

that's a U.S. phone number.

This call is most probably made from japan.Cause +81 is the international code of japan.

i think you are not allowed to post phone numbers. just a thought.
