Kazuchika Okada

Kazuchika Okada (岡田 和睦, Okada Kazuchika, ring name: オカダ・カズチカ) (born November 8, 1987) is a Japanese professional wrestler currently signed to New Japan Pro-Wrestling, where he is one-third of the current NEVER Openweight 6-Man Tag Team Champions in his first reign. Okada is a five-time IWGP Heavyweight Champion where his fourth reign with the championship is the longest in history at 720 days. He also holds the record for most successful title defenses with 12. After the title was unified into the IWGP World Heavyweight Championship, Okada has gone on to hold the new championship a record two times.

Initially trained by Último Dragón and making his debut in August 2004, Okada spent his first years in professional wrestling working in Mexico, before returning to Japan and making NJPW his home promotion in mid-2007. Originally working as a junior heavyweight, Okada graduated to the heavyweight division in April 2008, with limited success. In February 2010, NJPW sent Okada on a learning excursion to American promotion Total Nonstop Action Wrestling (TNA), where he spent the next twenty months, mainly performing on the promotion's secondary television program, Xplosion. From January to March 2011, he performed under the name Okato on TNA's primary television program, Impact!, as Samoa Joe's sidekick in his rivalry with D'Angelo Dinero.

Okada's run with TNA ended in October 2011 and he returned to NJPW in January 2012, repackaged as "Rainmaker" (レインメーカー, Reinmēkā), complete with a new look and a villainous persona. Just a month later, Okada defeated Hiroshi Tanahashi to win NJPW's top title, the IWGP Heavyweight Championship, which he would hold for four months before losing it back to Tanahashi. The following August, Okada won NJPW's premier tournament, the G1 Climax. At the end of the year, the Tokyo Sports magazine named Okada the 2012 MVP in all of Japanese professional wrestling. The following year, Okada first won the New Japan Cup in March and then regained the IWGP Heavyweight Championship from Tanahashi in April. After a thirteen-month reign, Okada lost the title in May 2014. Three months later, he won his second G1 Climax. Okada went on to win his third G1 Climax in 2021 and his fourth in 2022, which makes him the wrestler with the second-most wins in the tournament with four, just behind Masahiro Chono who has five. Okada has since won the IWGP Heavyweight Championship three more times and headlined NJPW's biggest annual event—Wrestle Kingdom—eight times (7, 8, 10, 11, 12, 14, 16 and 17).

Widely considered one of the greatest professional wrestlers of all time, he became the first Japanese wrestler to top Pro Wrestling Illustrated's list of the top 500 wrestlers in the world in 2017. Readers of the Wrestling Observer Newsletter named him as the most outstanding wrestler of the 2010s in March 2020. Okada's match with Kenny Omega at Dominion 6.9 in Osaka-jo Hall in June 2018 is regarded as one of the greatest professional wrestling matches of all time, and received a rating of seven stars by sports journalist Dave Meltzer, the highest rating Meltzer has ever awarded a wrestling match. Okada was inducted into the Wrestling Observer Newsletter Hall of Fame in 2021.
