The first wave of the fall prime time dramas started this week, and so far the big ratings winner is Fuji TV's "Iryu 2." The sequel to last year's popular medical drama kicked off on Thursday night with ratings of 21.0%. This is the 8th highest start for a Fuji TV series in that time slot. It is also the network's first drama to premiere at higher than 20% since last fall's "Dr. Coto's Clinic 2006."
