In the picture, there you see the 1/1 size statue of Gundam.
For those who don't know about Gundam, it is a military robot with the cockpit inside the body (although they don't have one in this statue) and it is from one of the most famous anime series in the history of Japanese anime.
I believe there are very few people in Japan who don't know anything about Gundam.
In a way, it is the origin and the symbol of all the Japanese popular culture that is continuing up until now.
The reason they made a 1/1 statue of Gundam at Odaiba goes back to 2009.
There was a project called "Green Tokyo Gundam Project" that was taken place from July 11 to August 31, 2009.
Its purpose was to promote the urban tree plantation in Tokyo, which is practiced with the cooperation of local government, citizens, and business industries.
Eventually they chose Gundam as a symbol of "the rebirth of Tokyo as a green area".
I don't know how this (practically) weapon of mass destruction is associated with the rebirth of life. But that is how the statue of Gundam was created and I'm sure a lot of Gundamanias (people obsessed with Gundam or even worship it as a religious deity) appreciated and still appreciating this work of art.
I think this is one of those things people recently call "only in Japan" in some part of the Internet.
And I think that is quite a characteristic of Japanese culture that the popular culture such as anime occupies relatively a large part of the Japanese society (I said "relatively", not the Japanese society in general).
I think (though I may be wrong) so far Japan is the only country in the world that set up the statue of a character that comes from anime as the public property.
That is something I barely hear from foreign countries (I'm not advocating the "uniqueness of Japanese culture" here).
