Shinya Hashimoto (橋本 真也, Hashimoto Shin'ya^?, July 3, 1965 - July 11, 2005), was a Japanese professional wrestler. Along with Masahiro Chono and Keiji Mutoh, Hashimoto was dubbed one of the "Three Musketeers" that began competing in New Japan Pro Wrestling in the mid 1980s and dominated the promotion in the 1990s.

He is one (the other being Keiji Mutoh) of two wrestlers that have held the NWA World Heavyweight Championship, the AJPW Triple Crown Championship and the IWGP Heavyweight Championship. He is often compared to All Japan Pro Wrestling's Toshiaki Kawada, as both are widely known for their stiff kicks and violent matches. As of 2010, he has the longest IWGP Heavyweight Championship reign in history, lasting 489 days.

Hashimoto grew up in Toki City in Gifu, and began training in judo in his late teens. His training helped him in his transition to professional wrestling, as he joined the New Japan Pro Wrestling Dojo in April 1984. He made his debut for NJPW in September 1984 at the age of 19, wrestling against Tatsutoshi Goto. Hashimoto worked on becoming a skilled wrestler over the next few years, travelling whenever necessary to gain more seasoning, such as over in the United States (Continental Wrestling Association), Canada (Stampede Wrestling), and Puerto Rico (World Wrestling Council). During his excursion in the United States, he visited the Elvis Presley museum in Memphis. Instantly, Hashimoto became a huge fan and because of this, his dressing up in Elvis costumes, and his sideburns, many of his peers commonly refer to him as "Fat Japanese Elvis."

Masato Tanaka (born February 28, 1973) is a Japanese professional wrestler, best known for his appearances with Frontier Martial Arts Wrestling in Japan and in Extreme Championship Wrestling in the United States where he was a one-time world champion, having won the ECW World Heavyweight Championship once. He is currently splitting his time working for New Japan Pro Wrestling and Pro Wrestling Zero1, where he is currently one half of the NWA Intercontinental Tag Team Champions.

Tanaka trained under Atsushi Onita, and debuted on July 23, 1993 in Saga City, facing Ricky Fuji. He quickly began working for FMW, widely regarded as the most hardcore professional wrestling promotion in Japan. Wrestling in matches featuring explosions and barbed wire, Tanaka earned a variety of scars, and the nickname "Dangan", which he would often shout during his matches. By 1996 he was one of the promotion's major stars, and had feuded with such luminaries as Mr. Pogo, Mr. Gannosuke, Terry Funk and Mike Awesome. His feud with Awesome would eventually span ten years and two continents. In December 1999, he left FMW for ECW, after he and Tetsuhiro Kuroda lost to H and Mr. Gannosuke.

Kazunari Murakami (村上 和成, Murakami Kazunari^?) is a Japanese freelance professional wrestler and a retired mixed martial artist, best known for his appearances in Pro Wrestling ZERO1-MAX and Big Mouth LOUD, of which he was a founding member. He was also part of the first fight in PRIDE history, defeating John Dixson by submission.

Murakami began his Mixed Martial Arts career fighting for the Lumax Cup: Tournament of J '95 on October 13, 1995 where he lost his first fight Akihiro Gono by knockout. A few months later, on March 30, 1996, Murakami fought at the Lumax Cup: Tournament of J '96. He fared better defeating Isamu Osugi by submission and avenging his loss to Gono by decision but lost to Masanori Suda by submission. In late 1996, Murakami then began fighting for Extreme Fighting where he defeated Bart Vale At EF3: Extreme Fighting 3 on October 18, 1996 by TKO. A few months later, at EF4: Extreme Fighting 4 on March 28, 1997, Murakami lost to future UFC Heavyweight Champion: Maurice Smith by KO.

Yuki Ishikawa (石川友紀 Ishikawa Yuki, born 26 April 1987) is a Japanese volleyball player who plays for JT Marvelous.

She plays for the All-Japan women's volleyball team and was a participant at the 2006 Volleyball Grand Prix. She maintains a Japanese language blog.

Shinjiro Otani (大谷晋二郎, born July 21, 1972) is a Japanese professional wrestler contracted to Pro Wrestling ZERO1. Otani is also the acting President of the company.

Otani was the first WCW World Cruiserweight Champion, defeating Wild Pegasus in a tournament final to be crowned champion on March 20, 1996. This was the start of his push as a legitimate junior heavyweight contender. Over the years, Otani earned the J-Crown and was also part of the first IWGP Junior Heavyweight Tag Team Champions with Tatsuhito Takaiwa.

In 2000, New Japan booker Riki Chōshū, eager to push his protege Kensuke Sasaki above everyone else, downgraded the junior heavyweight members to mere jobbers for the heavyweights. Otani protested and was sent abroad to bulk up. Returning in 2001 as a full-fledged heavyweight, Otani challenged Sasaki for the IWGP Heavyweight Championship, but failed.
