Nosawa Rongai

On August 27, 2017, Nosawa, as Black Tiger VII, teamed with Taka Michinoku to defeat Atsushi Aoki and Hikaru Sato for the AJPW All Asia Tag Team Championship. They lost the title to Naoya Nomura and Yuma Aoyagi on September 30.

Since April 2015, Nosawa joined the newly resurrected Frontier Martial-Arts Wrestling, as the leader of Monster-gun, which evolved into W*ING Monster-gun, when Kintaro Kanemura joined the group.

Since September 2013, Tokyo Gurentai, Nosawa included, has worked regularly for Wrestle-1.

On May 23, 2012, Nosawa and former girlfriend Io Shirai were arrested at the Narita International Airport in Narita, Chiba upon their return from Mexico to Japan under suspicion of trying to smuggle 75 grams of marijuana, hidden inside paintings of the two, into the country. On July 9, Mexico-based Japanese wrestler Takuya Sugi held a press conference and confessed to planting the drugs on Shirai and Nosawa. According to Sugi, Masahiro Hayashi, who worked as a liaison between AAA and Japan and who had a personal grudge with Nosawa, had promised him a contract extension with AAA in exchange for the deed.

On February 20, 2011, Nosawa was arrested on charges of stealing a taxi and driving it without having a driving license. Two days later Nosawa announced that he was taking an indefinite break from professional wrestling. Nosawa returned from his break on June 25 at a Minoru Suzuki promoted charity event, losing to Suzuki in the main event.

In 2007, Nosawa went on tour with JCW to film the Internet wrestling show SlamTV!, where he was one of the main heroes of the program. However, he started off his SlamTV! tour with a string of losses, going 0–5 in his first five matches. After receiving a letter from his storyline mentor The Great Muta, saying that Muta was coming to JCW to check up on his pupil, Nosawa stepped up his game and began a winning streak. At "East Side Wars", The Great Muta teamed with Nosawa to help him defeat the team of Mad Man Pondo and Necro Butcher. By the following week however, The Great Muta had left. Despite this, Nosawa continued his winning streak into episode 14, where he faced and defeated Ron Zombie. During the match, Justin Credible came to the ring and assaulted Nosawa. On the next episode, Nosawa interfered in Credible's match by spitting Asian mist into his eyes. At Bloodymania, Nosawa and The Great Muta teamed up again to defeat Justin Credible and 2 Cold Scorpio.

On October 6, 2007, Corporal Robinson, Scott Hall, and Violent J formed the Juggalo World Order (JWO) at Evansville Invasion. At that year's Hallowicked After Party, on October 31, Shaggy 2 Dope was introduced as a member of the group. After the main event of the night, special guest referee Nosawa ripped off his referee shirt to reveal that he, too, was a member of the JWO. Nosawa appeared in a few matches with the JWO, before returning to Japan.

In 2007, Nosawa promoted several comedy wrestling shows, making fun of Antonio Inoki's Inoki Genome Federation and using both talent from All Japan, as well as freelancers. During the Champion Carnival, Nosawa switched his name to El Nosawa Mendoza and formed a new stable called "Los Mexico Amigos", with Pepe Michinoku (Taka Michinoku) and Miguel Hayashi, Jr (Kaz Hayashi). Nobutaka Araya then joined the team as El Hijo del Araya Segundo after the Carnival’s final show. Along with changing their names, the group wore the official colors of the Mexican Flag (Red/Green/White). After multiple bouts against Minoru Suzuki, Nosawa offered Suzuki an invitation into Mexico Amigos, to which he declined. This resulted in the group changing multiple assets. Their name was changed to Mexico Amigos Black, the previous worn Mexican Flag attire became black and gold attire, and Araya was kicked out of the group. Later in the year, Mexico Amigos teamed with "Ray Suzuki" to defeat the team of Ryuji Hijikata, Kikutaro, T28 and Ryuji Yamaguchi. After the match, Ray Suzuki revealed himself as Minoru Suzuki. Suzuki stated that starting the next year Mendoza would throw his Amigos tights away and return to the Nosawa Rongai ring name, Suzuki then kidnapped Nosawa to start his "early training". This was followed by Pepe and Miguel announcing they would return to Mexico, while Kaz Hayashi and Taka Michinoku were announced as returning to All Japan come the new year. After one last "Viva Mexico", Los Mexico Amigos disbanded.

In 2006, Nosawa would begin again wrestling with his old friend Mazada again, and for parts of the year would also team with Brute Issei and Akira. Towards the end of 2006, Nosawa and Mazada began to team up with Minoru Suzuki to form "Minoru Gundan", which landed Nosawa a more prominent role in the promotion. He and Suzuki would go on to wrestle in the World's Strongest Tag Determination League, but unfortunately the team would come in last place.

Nosawa would originally find little success after arriving in All Japan Pro Wrestling (AJPW) in the mid-2000s, losing as many matches as he won. On March 20, 2005, he received an opportunity at the World Junior Heavyweight Championship, but would lose to defending champion Taka Michinoku. On July 26, he lost a "Banishment" match to his old friend Mazada, and was forced to leave All Japan. Soon after that, he would reappear as a masked wrestler named Space Lone Wolf (Keiji Mutoh's old alter-ego), finding more success than his previous character. However, by December, Space Lone Wolf would be unmasked and revealed as being Nosawa.

In 2004, he would adapt the "Nosawa Rongai" or "Nosawa Out of the Question" ring name as a play off to a comment made by Kaz Hayashi, who had replied "Nosawa is out of the question" when he was asked about whether he was going to allow Kazushige to challenge for the World Junior Heavyweight Championship. By doing this, Nosawa forced a title match against Hayashi, and although he lost, he would decide to keep the name for the rest of his career.

On March 16, 2003 at a Juggalo Championship Wrestling (JCW) event, Nosawa defeated "Ritchie Boy" Breyer Wellington to win the JCW Heavyweight Championship. Later that year, he was featured on JCW Vol. 3 in a match where he again defeated Wellington. In July 2004, Nosawa lost the championship to Kid Kash at the Gathering of the Juggalos. In 2007, he took part in the Pro Wrestling Unplugged/Juggalo Championship Wrestling cross promotional event "Cuffed & Caged: Last Man Standing". Nosawa was featured in the main event War Games match as a member of Team JCW.

Nosawa would first gain national U.S. exposure by making appearances for Total Nonstop Action Wrestling (TNA). He debuted at the 2003 Super X Cup, losing in the first round to Juventud Guerrera; he then reappeared as captain of Team Japan in the 2004 World X Cup, where he ended up placing last by the end of the tournament. Nosawa would go on to make sporadic appearances on the early episodes of TNA Impact, usually teaming up with fellow Japanese rookie Kazushi Miyamoto. The duo even challenged for the NWA World Tag Team Championship at TNA's second Anniversary show in June 2004, but ultimately came up short against America's Most Wanted. The duo's last in-ring appearance for the company would be at Victory Road '04, where both Nosawa and Miyamoto competed in the X-Division Gauntlet match, which was won by Hector Garza.
