I know that Yuzuru is from Sendai, one of the areas most affected by the earthquake and tsunami. However, I just read that his rink is still closed and that he has no "home ice" to train on because all the other rinks in Japan are full. So, apparently he made an appearance in over 60 ice shows in order to have practice ice!
Also, when the earthquake struck, he was on the rink, and had to evacuate in his skates!!
Add that to his battle with asthma, and the toughness and resilience of this 16-year old is mind-boggling. I already like him but this gives me even more reason to hope he this season. COC might be a disappointment any other time but when you consider all that he had to go through in the past half year... it's incredible.
