Google Japan released search ranking lists in a variety of categories for the year 2011. Some were based on number of searches while others focused on sudden increase in search volume.
Here are the top ten in the "sudden increase" anime category:
10. Hunter x Hunter
9. One Piece
8. Anpan Man
7. Toriko
6. Freezing
5. Suite PreCure
4. Steins;Gate
3. Usagi Drop
2. Mobile Suit Gundam AGE
1. Puella Magi Madoka Magica
Incidentally, in the overall search side of the lists, the live action adaptation of the Moteki manga made #8 in movies in general. It placed 6th in the Japanese movie category, followed by live action Gantz (#8), the new K-On! anime movie (#9), and live action Kaiji (#10).
Any surprises? I for one sort of expected to see some Tiger & Bunny action!
