Like Sakai and Kiyotake the most, for obvious reasons, Sakai has tons of potential to hit it big (seen two games of him, veeery dynamic), and Kiyotake reminds me a bit of Kagawa on that clip, except he can shoot...
Haraguchi is 3rd favourite simply because he is one insanely gunho aggressive runner. Jesus is he relentless mofo in some of those plays. Like a funny mixture of Olic, Pepe and Robben in some of his runs lol.
Little little Japanese Giovinco Ono looks nice (is the real Ono retired btw?), but that Yamada one is least impressive based on that clip, doesnt help his clip is from 1 game only (but checked others).
Btw Jay, who are your favourite Japanese players? Not just currently, in overall its still Nakamura for me hehe. In overall its him > Kagawa > Honda > Matsui > Endo > all of J-League players I never seen > Nakata
