Big O

Big O (ビッグ・オー, Biggu ō) is a centerless non-rotating Ferris wheel at Tokyo Dome City in Bunkyo, Tokyo, Japan.[1]

Big O has a diameter of 60 metres (200 ft), and was listed as the world's largest centreless Ferris wheel by Guinness World Records in 2006. Joysound karaoke machines were added to eight of its forty gondolas in August 2017.[2][3] Tokyo's largest roller coaster, the 130 kilometres per hour (81 mph) Thunder Dolphin, passes through the centre of the wheel.[1]
