The January 4 Tokyo Dome Show is a major professional wrestling show, held by Japanese professional wrestling promotion New Japan Pro Wrestling (NJPW), held annually on January 4 in the Tokyo Dome. NJPW often invites other promotions, Japanese and international, to participate in their January 4 Tokyo Dome Shows as well, including several companies that have been involved in scripted inter-promotional rivalries such as All Japan Pro Wrestling (AJPW), Big Japan Pro Wrestling (BJW), Pro Wrestling Zero1, Pro Wrestling Noah, and UWF International (UWFi) as well as representatives from the Mexican Consejo Mundial de Lucha Libre (CMLL) promotion. The shows have regularly featured wrestlers from American promotions such as Ring of Honor (ROH), Total Nonstop Action Wrestling (TNA), and World Championship Wrestling (WCW) and have on these occasions been shown either partially or in full in the American market.

It has become an annual event that starts the new year in NJPW since its inception in 1992. NJPW have held shows at the Tokyo Dome as far back as April 24, 1989, but their January 4 show has become the most anticipated show on NJPW calendar. It is Japan's biggest wrestling event and NJPW's premier show, similar to what the WrestleMania is for the WWE. The first two January 4 Tokyo Dome Shows were also the last two WCW/New Japan Supershows. Since 2007, when the event was renamed "Wrestle Kingdom in Tokyo Dome", the Dome shows have been broadcast on pay-per-view (PPV). As of 2017 all the Dome shows have featured championship matches, including several titles not owned by NJPW. On three occasions (1998, 2006 and 2013), no titles changed hands during the show. The 1993 Tokyo Dome show set the attendance record with 63,500 fans packing the Tokyo Dome, while the 2007 Dome show drew the lowest gates with only 18,000 in attendance. As of 2017, the January 4 shows have hosted 282 matches (not including dark or pre-show matches), 94 of which were title matches leading to 44 title changes in total. The 2005 Tokyo Dome show had a 16 match card, the largest of any of the shows, while 2001, 2002, 2007, 2013, and 2016 featured 9 matches, the lowest number of matches on a show.
