A free year as a BYOND member awaits you if you can identify the lady in my main icon...

Here are your clues:
1) She performed in the United States for three or four days at the beginning of the month.
2) She is from Japan is considered famous there.
3) I found it while browsing YouTube with my daughter.

Rules:
1) You can guess as many times as you want, but they must be made seperately in the comment box.
2) Don't be a jerk and guess 100 times.
3) If you already have a membership, you can gift it to someone else.

Good luck!

HINT #1: Why would I have clue #3 at all?

Congratulations Airjoe!
