Japan is getting a massive Splatoon Esports tournament with a $1 million dollar prize pool reported by Gameranx. The series called the ‘Splatoon Koshien 2016’ will be hosted by Kadokawa and Dwango and will see 4 cities holding 40 events starting with Fukuoka on September 13th.
The tournaments will run 4v4 Turf War matches with no weapon limitations. Entries are open but if they get too many applicants, it will be decided on lottery (like everything else popular in Japan)
There has been no announcement of any tournaments coming to the west but this would be fun to watch.
