I don't think it's fair to have Jinpachi Taki in the same pool H21, as Woo. Jinpachi is a strong Japanese player that competes in the Nishinipporri Versus weeklies and although he doesn't have tournament results to seed him, I don't think he should be in that pool.
Kyabetsu with Dakou in pool H23 seems questionable as well. Dakou will probably come out in losers from this pool.
Pam is a good japanese player (though not as strong as Jinpachi or Kyabetsu), might be questionable to put him in pool H26 with Verna.
