He says “I will be happy if I will be able to master 4A ultimately.”
I’ve seen over 30 news clips since last Saturday but I could not find a footage which captured his entire comment neither after SP nor after FS, and in some TV shows they quote his words out of context (the one about 4A is one of them.) Maybe it’s better to wait for a while till some magazine or figure-skating-related TV program will cover his whole interviews… or his longer interviews. These fragmented interviews are causing confusion even among Japanese speakers

Being able to see Yuzuru being Yuzuru after all these months is great though.
