The park is not very large, but there are a lot of things for children to do. First, there are some rides including a small ferris wheel, merry-go-round, mini-train, and pedal-powered 'sky' cars.
There is also a roller coaster that is known as 'the slowest roller coaster in Japan'. It was perfect for the 7 year old I took on my second visit. It was the only ride we did twice!Also in the park is an 'Animal Plaza'. In addition to some caged animals (monkeys, birds,...), there is a great petting zoo. Kids get a chance to get up close and personal with goats, deer, sheep, rabbits, and really cute guinea pigs! On a second visit to the park, the petting zoo was kept clean, but the waste in some of the other cages needed to be dealt with.
Many were enjoying a couple of small fishing ponds. This area was quite popular with older elementary school boys and their fathers. The park also contains some grassy picnic areas, some fast food outlets, and some great blow-up 'attractions'. There was also a live music performance the day I was there (traditional Japanese drumming, flutes,...).
If you just want to look around, the entrance fee is 200 yen for adults, 100 yen for children. For 1400 yen, and adult and child can enter together and they receive 12 tickets. Each ride 'costs' one ticket for a child, two tickets for an adult. Extra tickets can be purchased if necessary.

Transportation: The coolest way to get to the park is by the Toden Arakawa Streetcar, the last remaining streetcar in Tokyo. The train starts at Waseda or Minowabashi. It is also accessible by bus, by water cruise boat, and by car. Reasonable parking is available nearby.
