A veteran of multiple promotions, Taiji Ishimori has brought his speed, athleticism and ruthless mentality to earn success everywhere he goes. A member of BULLET CLUB since 2018, Ishimori has become a key player in the group. 

With laundry list of titles already under his belt in Pro-Wrestling NOAH, Ishimori’s first NJPW championship was the NEVER Openweight 6-Man tag title, which he won alongside G.o.D. in August 2018. The next January he won his first IWGP Junior Heavyweight Championship from KUSHIDA, and claimed the IWGP Junior Heavyweight Tag Team Championships with El Phantasmo the same year, before becoming IWGP Jr. Heavyweight Champion for the second time in August 2020. 

A third IWGP junior Heavyweight Championship reign came at the expense of El Desperado at Dontaku in May 2022. A formidable champion, Ishimori quickly scored his first defence over Best of the Super Jr. winner Hiromu Takahashi. Yet he would be reluctant to defend a second time, eventually only doing so at Wrestle Kingdom 17 in a four way match. Hiromu would win that four way bout, putting Ishimori back in the title hunting role.
