Ten popular fictional heroes in Japan

I was writing about "Hero Day" in Japan and it got me thinking about some of the famous fictional "heroes" in Japan. I searched to see if there are any statistics available about which heroes are the most popular, but I couldn't find any official statistics. It seems its hard to measure quantatively.

The first fictional Japanese hero that came to mind for me is ①Son Goku, from Dragon Ball. That is largely due to the fact that my son is a huge Dragon Ball fan! When I searched my personal photo collection for a photo of Son Goku, it brought up the photo in this post, which automatically triggered recollection of some of Japan's other famous heroes, as you can also see ②Doraemon and ③Ultraman.

Others that come to mind are ④Anpanman, ⑤Kamen Rider, ⑥Monkey D.Luffy, ⑦ Pikachu, ⑧Naruto Uzumaki,  ⑨Totoro Detective Conan and ⑩ Totoro. Without putting too much thought into it, those ten came to mind pretty quickly. But what isn't so easy is choosing my hero from among them!  Not just of this list, but of all the fictional Japanese heroes. How about you? Do you find it difficult to choose or do you have a favorite fictional hero that comes to mind instantly? I have also asked a similar question in the Q&A section of City-cost.
