This theme park has 3 main areas: the main park area where the rides are, the water park area (used for illuminations in the winter) and the newer semi-educational heavily sponsored area when you can design your own Nissin noodle cover and have it made into a professional product to take home, or ride around the SECOM pedal track, among other attractions. There is a large car park, or a gondola cable car from the nearest station (Keio Yomiuriland) up to the park - definitely try to use this in the winter as you get a great view of the illuminations. I don't recommend driving if you're going to the illuminations in the winter, it's popular and the roads get jam-packed.

Each winter, the illuminations design changes and it's always good. Very popular for children and families but also a good date spot for young adults, apparently.

In the summer, this is a good water park with 2 giant water slides, a rotating current pool, a wave pool (often with live music entertainment), a swimming pool (look out for the male lifeguard synchronised swimming performance) and well worth a visit.

It's way the place is definitely catered more to children than adults, but they do serve beer (in both the water park and main park) and some rides such as the space shuttle that goes upside down, rotating 360 degrees, are also good for adults. I don't rate the rides highly in general, as a tall adult, but the kids will have a great time!
