Japan in the World Cup - Samurai soccer in Brazil?

You will never believe what this youtube video is all about. See if you can guess based on the following:

1. There is a Japanese guy dressed up as a samurai;
2. He is not just good at soccer, he is incredible;
3. He is in Brazil wowing the crowds at the World Cup.

Here is another photo, only slightly different to the dressed up samurai. Which one do you like? What did you think of the youtube video? Are these the sort of things you have come to expect from the Japanese?
