I've heard about this place and was curious, though I hadn't been until now. It's a smaller version of Lego land inside Tempozan Marketplace that has 2 rides, a 4D movie, an Osaka mini that land goes from night to day(lights up and darkens), and several themed Lego build/play areas (duplo, the Lego friends, etc). One area lets you build a car and race/speed test on a special ramp. Upon entry it opens up into a surprisingly spacious area. There is also a cafe, break/lounge room, kids jungle gym, and several benches/seating areas. Be sure to get and fill the stamp collection book for free Lego prizes at the end. Speaking of which, there is a Lego store with plenty of souvenirs and Lego sets (some unique) to buy. For cleanliness, they sanitized the rides and play area hourly or so, and they spray all the Legos down until they're soaked. My 7 and 12 year old enjoyed the few hours we spent here, and we liked it too. Not a bad trip for around $20 apiece!
