The top attraction at this amusement park next to Tokyo Dome is the 'Thunder Dolphin' (¥1030), a roller coaster that cuts a heart-in-your-throat course in and around the tightly packed buildings of downtown. There are plenty of low-key, child-friendly rides as well. You can buy individual-ride tickets, day passes, night passes (valid from 5pm) and a five-ride pass (¥2600).

Also part of the Tokyo City Dome complex is the excellent space museum TeNQ.
