Based of all the uh...bickering on this thread about Yuzuru and his fans, I think it's pretty clear that big stars sell tickets more than anything else, even if some people are unhappy about that. Unfortunately, Yuzuru's combination of ungodly talent, charisma, good looks, and likeable public persona....
And his remarkable good sense in being born Japanese at just the right time
I could be wrong - people with longer histories in the sport feel free to say so! - but I vaguely recall reading somewhere that when Takahashi, Nobu, Mura etc were starting out, men's skating in Japan was something of a poor relation and not nearly as popular as it became: these guys built a solid fan base of varying but much-loved star sizes just in time for Yuzuru to come along and go supernova. Don't get me wrong, he would probably have been a superstar of the sport from most countries, but being said superstar in a country which already adored the sport gave his fame quite a springboard - ice shows, publicity, personal awards, TV coverage - to go international.
This business of the men building a fan base also buys in to what someone said about longevity and building loyalty for favourites rather than trying to manufacture more supernovas (there were supernovas before Yuzu, there will be after him, maybe not as soon or as big as the ISU would want) Look at how dearly Nobu is still loved in Japan, people will pay to go and see him or Takahashi personally (he's also just plain lovable, which in this day of pr and social media helps enormously. Ask Shoma and Jason and Mao)
