Alexander Otsuka

In 2006, Otsuka started competing in Michinoku Pro Wrestling under the gimmick of Otoko Sakari, a bisexual, sex addict wrestler who wore a fundoshi and utilized sexual antics against his opponents. Sakari never took off as a serious contender, as he often lost matches by nudity or morodashi when his opponent damaged his attire, making the ring crew throw the towel to cover it. Sakari feuded mainly with Kanjyuro Matsuyama, scheduling a 7-matches series to solve their enmity, which Sakari lost by 3-4, being forced to shave his pubic hair. Sakari would later appear also in Dradition Pro Wrestling, getting in a feud with Kikutaro.

Two years later, Otsuka returned to PRIDE to take part in the Grand Prix 2000, and was pitted against feared kickboxer Igor Vovchanchyn. Otsuka, who had worked a wrestling match the same day, was cornered by The Great Sasuke, and showed off further his pro wrestling roots by throwing a dropkick against Vovchanchyn. The Ukrainian landed several hard punches and knocked Otsuka down several times, but Alexander kept himself away from being finished and managed to stun Igor with a right punch, though still losing by unanimous decision. Although he was eliminated from the tournament, the Japanese came to fight the next event as well, taking on Pancrase and Ultimate Fighting Championship exponent Ken Shamrock, who won the fight by knocking Otsuka down and executing ground and pound.

Otsuka became one of the greatest Battlarts stars, feuding with Daisuke Ikeda and Yuki Ishikawa in violent matches and brawls, and being also part of the Love Warriors tag team along with Mohammed Yone. His career in the promotion was parallel to its very existence, ceasing when Battlarts folded in 1999, and doing a return when it reopened in 2002 with Pro Wrestling Zero-One's support. He also competed as a Battlarts representative in Zero-One, U-STYLE, Universal Fighting-Arts Organization and other promotions.

In 1998, Otsuka debuted in worldwide MMA for PRIDE Fighting Championships in PRIDE 4, the same event in which fellow pro wrestler Nobuhiko Takada had his rematch against Rickson Gracie. Otsuka was pitted against Marco Ruas, a Brazilian luta livre exponent from the Ruas Vale Tudo, while Alexander himself represented his home promotion Battlarts. Going against the pundits's judgement, Otsuka showed his skill and tenacity when he managed to take Ruas down and perform ground and pound through his guard, as well as later defending a fully locked rear naked choke to the end of the round. At the second one, Otsuka took Ruas down again and continued throwing punches, drawing blood from Ruas's face, and finally making the doctors call the fight. It was later revealed that Ruas fought under medication for hepatitis and a knee injury, but nonetheless the Japanese press lauded it as one of the biggest upsets ever, and Otsuka won the Tokyo Sports magazine topic award for his victory.

Otsuka made the move from a successful professional wrestling career to mixed martial arts competition in 1995. He earned a notable victory over Vale Tudo pioneer Marco Ruas in 1998. Though Otsuka finished his career in 2006 with a 4-13 record, he mostly faced very high-ranked opponents, including all-time greats Renzo Gracie, Ken Shamrock, Igor Vovchanchyn, Quinton Jackson, Wanderlei Silva, and Anderson Silva, all of whom defeated him. Otsuka was famous for his toughness in the ring.

Otsuka had his first contact with mixed martial arts when he was sent as a PWFG representative to the Lumax Cup 1995, a tournament of gi-clad MMA, but he was submitted in less of a minute by Shooto representative Egan Inoue. Afterwards, he had a short stint in Fighting Network Rings, losing to Chris Haseman by doctor stoppage from a cut at the event Extension Fighting 2. He retaliated by defeating Haseman in another Rings event, Battle Genesis Vol.2.

A former amateur wrestler since highscool, Otsuka was contacted by Yoshiaki Fujiwara to train in Pro Wrestling Fujiwara Gumi. Takashi debuted in 1994 under the name of Alexander Otsuka, a tribute to Alexander Karelin. He went to compete in the promotion until its closure, time in which he moved to Battlarts.

Takashi Otsuka (大塚 崇 , Ōtsuka Takashi, born July 17, 1971) , better known by his ring name Alexander Otsuka and Otoko Sakari, is a retired Japanese mixed martial artist and professional wrestler. Having competed for multiple pro wrestling organizations in his career, most recently with Antonio Inoki's Inoki Genome Federation, he is known for his work in the promotion Battlarts.
