One curious occurrence this weekend: in the B block of Division II, the four bottom teams in the division defeated the four top ranked teams. Cannot ever remember that happening.
Who knows if the weather had anything to do with it: on the new field at Tokyo Institute of Technology on Saturday, it was 42 degrees (107 F) by the time of the kickoff of the second game.
As is the case in most divisions in Japan, games are scheduled approximately two week(ends) apart.
