Watch a short film of Kanto versus Kansai Old Boys at Koshien Stadium, 1936. The linesman's flag bears the JFA's three-legged crow.
This round matches 47 prefectural champions, the 2015 university champion, 22 J2 clubs, and two of the three clubs most recently promoted to J1.
As usual, I'm completely biased in favour of northern Japan. When was the Emperor's Cup last won by a club from north of the 36th parallel? 1935, and it was Kyungsung FC, from Seoul, Korea. The clubs most likely to end the north's cup drought are: Vegalta Sendai (10th in the 2016 J1 First Stage), Albirex Niigata (13th in the 2016 J1 First Stage), Consadole Sapporo (currently 1st in J2).
