So here I was, successfully found it, Sanrio Puroland a.k.a Hello Kitty World. It was already closed when I reached there but I didn't think of entering even if it was still opened to public. I am no Hello Kitty fan.
So it was just a "been there (outside only), done that (selfie)" kind of thing but I was glad I went there. Just in case I was thinking of visiting Hello Kitty and friends next time, I will be sure of which route to follow.
