Ironman Heavymetalweight Championship

The Ironman Heavymetalweight Championship (アイアンマンヘビーメタル級王座) is a professional wrestling championship created and promoted by the Japanese promotion CyberFight in its DDT Pro-Wrestling (DDT) brand. Open to anyone, regardless of gender or DDT employment status, the championship is defended "24/7", as in any time, anywhere, as long as a referee is there to confirm the win. Because of this rule, not only is the championship winnable regardless of gender or number of individuals (in case of a common pinfall or submission), it is also available to "unconventional" champions such as animals or inanimate objects, with title changes regularly occurring outside of regular shows, often with videos posted on the promotion's social media accounts. The current champion is Danshoku Dino, who is in his 38th reign.

The championship was introduced on the June 29, 2000 TV taping, during which Poison Sawada Black created the title and awarded it to himself. It was created as a parody of the now-defunct WWE Hardcore Championship, which also had a "24/7 rule". The title is often defended during a 10-minute battle royal, with the current holder not being allowed to leave the match until the end of the time limit; as per 24/7 rules, the championship can change hands during, and not only as the result, of the match. Despite its name and similarly titled championships, it is not specific to Iron Man matches.

History
On November 2, 1998, Mr. McMahon awarded Mankind the World Wrestling Federation (WWF) Hardcore Championship. As Mankind and hardcore wrestling became more popular with audiences, the Hardcore Championship became a more serious title. Its popularity led competitor World Championship Wrestling (WCW) to create its own Hardcore Championship, a move followed by numerous independent promotions. When Crash Holly won the belt on February 22, 2000, he introduced the "24/7 rule" that the belt was to be defended at all times as long as a referee was present.

On June 29, 2000, Poison Julie Sawada introduced the Ironman Heavymetalweight Championship in DDT as a parody of the WWF Hardcore title and recognized himself as the first champion. Minutes after the unveiling, Mitsunobu Kikuzawa demanded he had a look at the title belt. He then used it to attack Sawada and pinned him to become the second champion.

The 1,000th Ironman Heavymetalweight Champion was crowned on April 29, 2014, when the title belt itself became the champion by pinning Sanshiro Takagi. At Ultimate Party 2023, the championship belt was won by a different title, the IWGP Junior Heavyweight Championship which pinned its holder at the time, Hiromu Takahashi, only to lose the Ironman title seconds later to Kazuki Hirata.

Belt design
The championship belt design features three glittery silver plates on a black leather strap which has a snake skin pattern on the back. The central plate features brass knuckles surrounded by chains in the center. The word "IRONMAN" is written along the edge of the top half and the word "CHAMPION", though partially erased by years of wear and tear, is written along the bottom edge. The two side plates, on either side of the central plate, are rectangular and identically state "24 HOURS" ("24" in silver bordered with black; "HOURS" in Japanese text in red).

Reigns
As of July 29, 2024, there have been 1,660 officially recognized reigns between 423 different human individuals, 7 teams and 56 inanimate objects and animals. The record for most reigns is held by Shinobu, who won it 216 times, including by trading the title back-and-forth with 215-time champion Yuko Miyamoto a total of 303 times on the same night. Danshoku Dino holds the record for longest combined reign with at least 448 days and counting (the exact date of when he won his tenth title is uncertain). Masa Takanashi's sixth reign is the longest singular reign at 333 days. Only 155 individuals have held the title for longer than a day. The title has occasionally been won by unusual means, such as an auction for the belt, rock–paper–scissors, and even a title change that occurred in a dream.

Non-wrestlers to have held the title include AV idol Nao Saejima, TV personality LiLiCo, J-pop idols Akari Suda, Kaori Matsumura, Yuki Arai, Rise Shiokawa, Aika Sawaguchi, Misaki Natsumi, Momomi Wagatsuma and Lingling, Tokyo Metropolitan Assemblyman Shinichiro Kawamatsu, a cat named Bunny, a monkey, a three-time champion ladder, Vince McMahon's Hollywood Walk of Fame star, a copy of The Young Bucks' autobiography Killing the Business, and the title belt itself.

Notable champions
As of November 2022, there have been over 1,500 title changes for the belt, which has been won by numerous male and female wrestlers and non-wrestlers, including children, animals, entire audiences and inanimate objects.

Animals

 * Yatchan - A monkey
 * Cocolo - A miniature Dachshund dog
 * Bunny - A cat

Inanimate objects

 * Ladder - a steel ladder. Would fall on the champion and a pinfall was counted. Ladder successfully defended the title by not being pinned during the time limit battle royal matches. Ladder was a three-time champion and the first inanimate object to win the title.

 * Yoshihiko - An inflatable 'love doll' and the supposed brother of Akihiro. Wrestlers treat it as if it actually was an active wrestler, and actually sell moves "done" by him/her, mostly high flying moves. For some moves, like outside dives, Yoshihiko is helped by one or more assistants, who throw him out of the ring, pull his foot on the ropes, etc. Opposing wrestlers act as if those assistants are not there and are part of Yoshihiko. The original Yoshihiko was "killed" by an Antonio Honda knee drop, which caused its head to burst open, and was replaced by a second Yoshihiko, who was also a 'love doll', only modified to resemble the Great Muta. The second Yoshihiko was killed by Kenny Omega by a giant swing that sent Yoshihiko out of the ring, thus splitting his head open and revealing cotton stuffing. Later on in that match however, a third Yoshihiko came out resembling The Undertaker's old American Bad Ass gimmick, even using the same theme music. Following that match, the third Yoshihiko was shot to death by Antonio Honda. A fourth Yoshihiko, resembling Hulk Hogan, debuted shortly afterwards.
 * Akihiro, another inflatable 'love doll'. Made its debut on August 18, 2013.
 * Vince McMahon's Hollywood Walk of Fame star
 * A bus
 * TV Tokyo camera crane
 * Pork bun
 * A kotatsu table
 * A trash bin
 * Pair of chopsticks
 * RN: Konyamoanokodenuitarou - A printed E-mail

 * An apple
 * A christmas tree
 * Stefan the Dinosaur - Unagi Sayaka's stuffed dinosaur
 * Maya Yukihi's whip

Non-existent

 * Arnold Skeskejanaker - An "invisible wrestler" i.e. non-existent. Opponents sell moves of a wrestler who isn't there, and the title is held by nothing and no-one but the wrestlers and referees act as if they can see and pin the "invisible wrestler". Muscle Sakai "won" the title from this "invisible wrestler" by using a "ray gun" and "infrared visor" to shoot the "invisible wrestler", winning the belt on a KO decision.
 * The Invisible Man - Another "invisible wrestler"
