BJW Ante Up

Ante Up was a professional wrestling supercard event produced by Big Japan Pro Wrestling (BJW). The event took place on December 2, 2001, at the Yokohama Arena in Yokohama, Kanagawa, Japan. The event was themed around BJW's interpromotional rivalry with American promotion Combat Zone Wrestling (CZW).

In the main event match, Daisuke Sekimoto and Men's Teioh defeated Kintaro Kanemura and Ryuji Yamakawa to retain their BJW Tag Team Championship and win Kanemura and Yamakawa's WEW Hardcore Tag Team Championship. In the semi-main event match, CZW's Zandig defeated Mitsuhiro Matsunaga in an exploding glass, light tubes and thumbtacks death match to win the BJW Deathmatch Heavyweight Championship; in other prominent matches, Ruckus defeated The Winger and Trent Acid in a three-way match to win the vacant BJW Junior Heavyweight and CZW World Junior Heavyweight Championships, Badboy Hido defeated Shadow WX in a barbed wire boards death match, and Justice Pain defeated Nick Gage to retain the CZW World Heavyweight Championship.

The event also notably featured the BJW debuts of Mil Máscaras and Terry Funk.

Background
In early 2000, Big Japan Pro Wrestling (BJW) established a working relationship with American promotion Combat Zone Wrestling (CZW); both promotions emphasized the deathmatch style of wrestling. As part of the working relationship, a stable of CZW wrestlers, dubbed the "CZW Warriors", invaded BJW to start an interpromotional feud. Numerous CZW wrestlers would tour Japan as part of the CZW Warriors including Wifebeater, Nick Gage, Trent Acid, Justice Pain, Johnny Kashmere, Nate Hatred, Ruckus, Nick Berk, "Sick" Nick Mondo, Mad Man Pondo, and Zandig among others. Members of the CZW Warriors would win BJW championships as part of the working relationship and BJW wrestlers would, in turn, tour the United States and win various CZW championships.

In 2001, BJW announced that they would be holding an event at the Yokohama Arena on December 2, titled Ante Up. The event would be themed around the ongoing BJW-CZW interpromotional feud.

Storylines
Ante Up comprised ten professional wrestling matches, that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed heroes, villains, or less distinguishable characters in scripted events that built tension and culminated in a wrestling match or series of matches.

Aftermath
Following the semi-main event match, Zandig cut a shoot promo on BJW, during which he announced the conclusion of the BJW-CZW working relationship. Zandig would take the BJW Deathmatch Heavyweight Championship belt that he won from Mitsuhiro Matsunaga during the match back to the United States following the event. The championship would later be declared vacant by BJW but CZW would continue to use the physical belt to represent their CZW Death Match Championship for the next two years before returning the belt to Japan.

The event was attended by 11,923 spectators; this remains the largest attendance in BJW history.
