I found a place where Meiji Jingu HS games were archived (at least the championship), and if you couldn't tell from the title, Nichidai-san wins the Meiji Jingu tournament 4-1 over Kagoshima Jitsugyou!
That means that Kokugakuin Kugayama is the favorite to receive the bid, and the floating bid for the Kanto/Tokyo super-regions will go to Kanto!
I'll give a full game recap of the championship as well as any other games that may be archived as time allows.
(Edit: Well nuts. The place that had the archive deleted all the archives. Probably didn't want to get the channel taken down...)
