Skateboarding is prohibited on the grounds of most public facilites such as schools, libraries and community centres. However, you sometimes see people skateboarding in public areas that aren't used that much, such as overflow parking areas when they are not in use. The most common place you see people skateboarding is in suburban housing areas in front of their own homes. The safest place to skateboard though, if you are unsure of the law and the manners, is in a skateboard park.
There are three skateboard parks that I know of in Saitama.
Kounosu Skate Park, in Kamiya public park, is only 200 yen to use for locals (100 yen for children), and 400 yen for non-residents (200 yen for children). They rent out skateboards and helmets.Occasionally, they have skateboard lessons.

In Kita Ward Saitama City, FUST BMX and MTB Park (by Felem Skate Park build and design), is 500 yen for the day . http://www.fust.jp/park/ Each park has a set of rules which include the need for protection and for young children to be accompanied by adults.
In Kawaguchi there is a free skate park for more advanced skateboarders. They do allocate a time on Saturday morning for children. They have their guidelines posted in the park in English as well as Japanese. The address is 1 Namiki Motomachi, Kawaguchi, Saitama 332-0033.
