When

The youngest person to reach a perfect 'AAA' rating on a Dance Dance Revolution game on the expert difficulty setting is Ryota Wada (Japan) who mastered the song 'Hyper Eurobeat' aged 9 years 288 days at his home in Wakayama, Japan, on 29 August 2010. Featured in Guinness World Records Gamers Edition 2011.

Ryota has been playing DDR since he was five, achieving highly respectable scores but missing out on the elusive 'AAA' rating due to the mat slipping under his feet. All it took for him to reach a perfect score was non-slip surface and the record was his.
