The first two editions in 2017 and 2018 had no stakes other than bragging rights. In 2021, the tournament made a comeback with LEC, Inc. as a sponsor. This edition crowned the inaugural Spirit of Ganbare World Openweight Champion.[1]
The 2017 Ganbare☆Climax was held from August 11 to August 13. The first two rounds were held on individual nights, with round one taking up the entire card on August 11.[2][3]
The 2018 Ganbare☆Climax was held from August 11 to August 12, and featured only eight participants. Two of the first round matches were held under No DQ & No Ropes rules.[7]
On September 25, 2021, GanPro announced that the Ganbare☆Climax was returning for a third edition sponsored by LEC Cleanpa! that would run from October 24 to November 23.[1][10][11] The tournament featured fourteen participants (two of which would receive a bye to the second round) and was won by Tatsuhito Takaiwa who was then crowned the inaugural Spirit of Ganbare World Openweight Champion.[12]
