Strikeforce will make their Japanese debut April 10th, 2011 during the afternoon hours in order to be shown live in the United States.

The fight card will consist of a lightweight portion, and the heavyweight grand prix second round.

Strikeforce will be working with Real Entertainment and possibly M-1 to co-promote the planned event.

The second round of the Strikeforce heavyweight tournament is:
Alistair Overeem vs. Fabricio Werdum
Josh Barnett vs. Brett Rogers

As M-1 is referred to as a possibnle co promoter, should that come to pass, presumably Fedor Emelianenko would appear on the card as well.
