Did you know there are 15 public holidays in Japan??!http://www.worldtravelguide.net/japan/public-holidays
It is in the middle of the Golden Week in Japan and many parents are having hard time thinking where to take kids. Many people may still feel it is not the right time to go too far because of the earthquake aftermath, but they cannot put kids at home for long holidays.
Here is an idea I found in free paper the other day... See the carps floating in air near Tokyo Tower, celebrating May 5th of Children Day.
It might be crowded inside the Tower but it is worth looking at the Tokyo Tower at the back of 'Koinobori' (The Carps in the picture) for Children Day.

Hope it would be a lovely day.
