The G1 Climax is a professional wrestling tournament held each August by the New Japan Pro-Wrestling (NJPW) promotion. Though it has sometimes been held as a single-elimination tournament, it is usually – and currently – held as a round-robin, with the most victorious wrestlers in each pool wrestling in a short tournament to decide that year's winner. Since 2012, the winner of the tournament earns the right to challenge for the IWGP World Heavyweight Championship at the following January's Wrestle Kingdom show.
