Mmmm... I don't know if this can work with you, but this is the way I always get my new sword's toku so fast. First, make sure your Iwatooshi is lvl 10 and then, make a group of low swords and train them on map 4-3 or 4-4, make Iwatooshi the leader and don't go to the boss node, in that way you don't spam Kebiishi. Be sure is a team where they can win, when he get his toku, you need to send him to refinery and max all hsi levels. Still as leader, with your level up swords train him.

That's how I train mines, actually I'm doing that with my Mikazuki, I won him yesterday and now he is level 30. Good luck!
