Kōrakuen

Accidently I went to Tokyo Dome City Attractions. It's an amusement park (which was formerly known as Kōrakuen until 2003.

 

 

According to Wikipedia, Big O is a centerless Ferris wheel and was listed as the world's largest centreless Ferris wheel by Guinness World Records in 2006.

 

 

The roller coaster passes through a hole in the building of shopping centre, and through the centerless Ferris wheel as well. It was not this amusement park, but a roller coaster reminds me of my grandmother. When she went to an ammusement park with her friends in her 50's, she thought it might be the last chance to ride on a roller coaster, and she rode in the front seat. How brave she was! She was a very spirited woman:)
