Ezaki initially competed for FMW as a low-carder between 1991 and 1993 before travelling to Mexico where he developed the "Hayabusa" character and his signature wrestling style during his time with lucha libre organizations.

He and Honda would struggle in the very small indy circuit for four years before joining Frontier Martial Arts Wrestling's dojo, headed by another former AJPW alumnus Tarzan Goto.

[16] In September 1993, Ezaki participated in a tournament for the inaugural Independent World Junior Heavyweight Championship, where he lost both matches in his block against Koji Nakagawa[17] and Battle Ranger Z.

[18] His last match in FMW during this tenure was a win against Masato Tanaka on September 27,[19] before Atsushi Onita sent Ezaki overseas to learn the lucha libre style in Mexico.

[20][21] The following month, Hayabusa debuted for CMLL on May 17 by teaming with Ringo Mendoza and La Sombra to defeat Javier Cruz, Panico and Tornado Negro in a two out of three falls match.

[24] He then returned to CMLL to team with fellow Japanese wrestler Último Dragón in the 1994 Copa de Oro on October 25 in a loss to eventual winners Apolo Dantés and El Dandy in the quarter-final.

[2] Hayabusa returned to FMW at the 6th Anniversary Show, where he unsuccessfully challenged Onita for the Brass Knuckles Heavyweight Championship in an exploding cage barbed wire deathmatch.

He wrestled the group's members in several tag matches for the next one month after Lethal Weapon questioned his ability to become the ace of FMW and vowed to take over the company.

[30] Hayabusa's team lost but the Phoenix Splash was heavily promoted by the Japanese media, which helped FMW in regaining the fanbase and Ezaki started becoming popular due to his high-flying skills.

[2] Just one month after his re-debut, Ezaki was booked to win the promotion's top title, the vacant Brass Knuckles Heavyweight Championship by defeating Lethal Weapon member Hisakatsu Oya on June 27 by debuting his new finishing move, Falcon Arrow.

[40] Ezaki competed against W*ING and Lethal Weapon members in various tag team matches, street fights and deathmatches throughout the rest of the year and early 1996 before taking time off due to multiple injuries.

[41] Despite the injury, Hayabusa returned to FMW on March 30 to rescue Jason the Terrible from an assault by Mr. Pogo and The Headhunters to set up the main event for the company's 7th Anniversary Show on May 5, where he teamed with Masato Tanaka to take on Pogo and Terry Funk in a no rope explosive barbed wire time bomb land mine double hell death match and the winner would receive one million yens.

On March 19, Hayabusa got his first title shot in nearly two years as he and Fuji challenged The Headhunters for the Brass Knuckles Tag Team Championship in a losing effort.

[54] On August 31, the trio of Hayabusa, Nakagawa and Masato Tanaka defeated Oya, Gannosuke and Gladiator to win the World Street Fight 6-Man Tag Team Championship.

[57] On October 14, Hayabusa, Nakagawa and Tanaka dropped the six-man tag team title to ZEN members Atsushi Onita, Hido and Tetsuhiro Kuroda.

[48] Hayabusa and Shinzaki participated in AJPW's 1997 Real World Tag League and kicked off the tournament on November 19 by defeating Giant Kimala and Jun Izumida.

[62][63][64][65][66][67][68] Hayabusa and Masato Tanaka faced Mr. Gannosuke and Yukihiro Kanemura in a losing effort for the vacant Brass Knuckles Tag Team Championship on November 28.

[70] On December 20, Hayabusa, Hisakatsu Oya and Masato Tanaka won the World Street Fight Six-Man Tag Team Championship by beating Atsushi Onita, Hido and Tetsuhiro Kuroda during the Super Extreme Wrestling War tour.

[88] On September 1, Hayabusa successfully defended the Double Championship in his third defense against Hisakatsu Oya[89] after the duo wrestled to a thirty-minute time limit draw.

[8] On January 16, 1999, Hayabusa reunited with Jinsei Shinzaki at an AJPW show to challenge Tamon Honda and Jun Izumida for the All Asia Tag Team Championship in a losing effort.

[126] On May 28, H competed against Gannosuke and Tetsuhiro Kuroda in a three-way dance to determine the #1 contender for the WEW Heavyweight Championship with the champion Kodo Fuyuki as the special guest referee.

[128] On June 26, H won the WEW 6-Man Tag Team Championship with Hisakatsu Oya and Tetsuhiro Kuroda by defeating Kodo Fuyuki, Kyoko Inoue and Chocoball Mukai.

[9][129] On July 22, Ezaki retired his H character and announced that he would begin competing as Hayabusa again after he and Tetsuhiro Kuroda defeated The Samoans (Eddie Fatu and Matty Samu).

[48] Hayabusa made his in-ring return at the 12th Anniversary Show on May 5 by teaming with Sasuke to defeat Kuroda and Gannosuke in an octagon cage electric bomb death match.

[141] On May 22, Hayabusa defeated Kuroda in a double hell barbed wire deathmatch to win the WEW Heavyweight Championship, with Kodo Fuyuki as the special guest referee.

[144] On August 3, Hayabusa offered to put his 5% stock if he, GOEMON and Onryo lost the six-man tag team match to Mr. Gannosuke, Kintaro Kanemura and Mammoth Sasaki.

The match took place on October 22, during which Hayabusa had a career-ending injury when he attempted a springboard moonsault off the middle rope and lost footing, landing on his head, cracking two of his vertebrae and leaving him paralyzed.

They fought almost one year exactly before this and Hayabusa smoked Gannosuke as a worker" and considered it "a worthy main event between two excellent wrestlers and undoubtedly the best match on the show.

"[159] Many of the industry's wrestlers like Chris Jericho, Jonathan Gresham,[160] Jack Evans,[161] AJ Styles, Pac, Will Ospreay, Samuray Del Sol, Kota Ibushi, Matt Sydal, Ricochet, Seth "Freakin" Rollins[162] and Mustafa Ali[163] were inspired by Hayabusa at some point in their careers.

He portrayed the main character's best friend Fuyuki Hayato, an injured air pilot soldier in World War II, who is reliant on a wheelchair.
