Yoshiaki Yatsu, Ashura Hara, Shunji Takano, The Great Kabuki, Hiromichi Fuyuki, Tatsumi "Koki" Kitahara, Masao Orihara, Isao Takagi (the future Arashi), and referee Hiroyuki Umino joined in from All-Japan.

The feeling was compounded when in October, SWS signed a working relationship contract with Vince McMahon's World Wrestling Federation, for interpromotional purposes.

SWS's peak coincided with the general Japanese economic downturn of the early 1990s, though AJPW and NJPW continued to do good business during that period.

Tenryu mainly battled foreigners such as Hogan and Flair since none of the other Japanese wrestlers in SWS were positioned as being at or near his level.

Yoshiaki Yatsu, who defected from AJPW three months after Tenryu, was added to Geki Dojo to give the group a senior level star.
