It's official. Sportsnavi is reporting that Saku is joining Heros. Saku said that since end of March he has left Pride and opened his own gym, he was free. As Tanigawa is a huge fan of Saku and always wanted him for K-1, he is very happy that Saku has now joined. Saku said that he wants to fight Black Mamba as his first fight.
Saku also said that he would like to fight for Pride again too (He wants to do both). He would like the two promotions to work closer together.
