Tokyo Dome.
Didn't know this place existed until I accidentally booked in a hotel here.
And what a treat to find that there was a little theme park attached to the mall right next to it. That said, despite my best efforts I was unable to get Shelly to ride the roller coaster, but after a bit of negotiating she agreed to the ferris wheel.
I feel like an idiot for not realising that there was something different about this wheel. It doesn't have any spokes. And the roller coaster passes right through the middle of it. I didn't notice. Daft!
