This is a common sight at festivals throughout Japan. I do not know half of the characters portrayed but I recognize Doraemon. My favorite is Ultraman.
I have been teaching English as a second language for over 20 years in Japan and Canada. What keeps me in Japan is the love of its culture, which constantly surprises me. I am also fascinated with "alternative travel", or "travel off the beaten path". Ferries and trains are my mode of choice... airplane for convenience.
