I thought I'd add this to my previous tip, as this outdoor area is great for kids and my 2 year old loved it.
I really recommend the Railway Museum for people visiting the greater Tokyo area with small children.

Trains are very much part of the fabric of life in Japan, and Japan has a very extensive railway network.
It's no surprise then that such a museum exists. In fact it was reopened on this sprawling site several years back.
You'll see a variety of trains from different eras, and there is quite a display on the history of the railroad in Japan and elsewhere.
It is very kid friendly, and there are tons of them there.
There is a lot more English language commentary than when I first visited, so more accessible than it was for non-Japanese speakers.
Entrance is 1000 yen for adults, and 500 yen for children.

For long term Saitama residents there is nothing better than a visit to the grounds of the Omiya Jinja (temple). A local temple with a long stand of trees, parkland and ponds. The trees are the last remnant of a grove that stretched all the way to Tokyo, part of a road unifying the great centres. Another great journey (within this most populated niche of Japan) is to the mountains of Chichibu. unlike other mountain pleasure spots in Japan this place is almost completely devoid of souvenir stores and loud tours. Instead you can sit almost completely alone on the stone riverbanks or spend an afternoon in a bamboo shaded teahouse. There is a reason for it not to future too prominently on tourist paths, it doesn't have the majesty of other mountainous areas however it does have a gentle pace and plenty of greenery within a short journey from Tokyo. Ideal for homesick Aussies.
