IWGP Tag Team Titles on six occasions and also won the very prestigious IWGP Heavyweight Title in 1998. In 2002, Chono won his fourth G1 Climax tournament and had a brief, memorable feud with WWE's Chyna. He also became a booker for NJPW around this time. In 2003, Chono briefly joined Pro Wrestling NOAH for a handful of matches and was defeated by GHC Champion Kenta Kobashi on 2 May of that year. On October 13, he lost to Hulk Hogan. Black New Japan and ChoTen (2004–2007) In early 2004, Chono became the leader of the Black New Japan stable, which was the most dominating heel stable in NJPW until it was disbanded by Riki Choshu. As a reaction to this, Chono lead an "Anti-Choshu Army" with Hiroyoshi Tenzan and Black Strong Machine. Chono won the 2005 G1 Climax tournament, thus having achieved a record-setting five G1 victories. His success in the G1 has given him the nickname Mr. August. On October 30, 2005, Masahiro Chono and Tenzan defeated the team of Shinsuke Nakamura and Hiroshi Tanahashi to win their fifth IWGP Tag Team Championship. The team went on to rename themselves Cho-Ten, a portmanteau of the members' names. They were stripped of the titles in late 2006 after they split up, and refused to defend them together. Masahiro Chono formed a stable with Shinsuke Nakamura in 2006 called Chono and Nakamura-gun, which began feuding with Tenzan's new group, GBH. Legend (2007–2010) Chono continued to wrestle full-time in 2007, but also began working as a promoter, with New Japan permitting him to set up cards in different areas of Japan. Following the 2007 G1 Climax, it appears that Chono may be breaking away from his BLACK faction and formed the Legend stable, having sworn in wrestlers such as Riki Choshu, Jyushin Thunder Liger, Shiro Koshinaka, and AKIRA. Outside wrestling, Chono began appearing on Gaki no Tsukai's "No Laughing Batsu Game" as one of the attackers, usually giving Hōsei Tsukitei a slap to the face. In January 2010 it was reported that Chono would be leaving New Japan and becoming a freelancer, after spending most of his career with the company. Later career (2010–2023) In March 2010, Chono portrayed Nobunaga Oda in two matches during a Samurai Festival after leaving New Japan. Chono wrestled AKIRA, who portrayed Mitsuhide Akechi, on both days, winning the first match and losing the second. On
