RB Ōmiya Ardija (RB大宮アルディージャ,Arubi Ōmiya Arudīja)[a] is a Japanese professionalassociation football club based inŌmiya,Saitama Prefecture. Its "hometown" (as designated by the league) is shared with neighboursUrawa Red Diamonds. The team currently play inJ2 League, the Japanese second tier of professional football, after promotion from the third tier in2024.
The club was known asŌmiya Ardija (大宮アルディージャ,Ōmiya Arudīja), before club administration was taken over byRed Bull GmbH in late November 2024 who renamed the club.


Ōmiya Ardija's original crest features a squirrel on the right, which is the animal of Omiya. On the left, there are 5 lines, which reference the historic roads that run through Omiya, including the famousNakasendō, which runs to theHikawa Shrine, right near Nack5 Stadium.[2][3]
On 6 November 2024, Ōmiya Ardija officially change crest and name toRB Ōmiya Ardija after being acquired by Red Bull GmbH from 2025.[1] The club retained their colours but adopted a new logo which is identical to other Red Bull owned clubs.
The former nickname of Omiya is Risu,squirrel inJapanese.
The team were founded in 1968 asNTT Saitama Soccer Selection inUrawa, Saitama and later known as the NTTKantō Soccer Club in 1969. They were first promoted to theJapan Soccer League (JSL) Division 2 in1987/88, and when the JSL folded, joined theformer Japan Football League.[4]
In 1998 the club was separately incorporated as NTT Sport CommunityK.K. based in Ōmiya to participate in theJ. League. The name "Ardija" is atranscription of theSpanish languageardilla (squirrel) which is themascot of Ōmiya and the park in which their home stadium is located.[4][5]
Their matches againstUrawa Red Diamonds have been called the "Saitama derby".[6]
From 2005 to 2007, most of Ōmiya's home matches were held atSaitama Stadium 2002 andUrawa Komaba Stadium due to expansion works at their home ground. In October 2007 the expansion was complete. On November 11, the re-opening match was held as a J. League season match between the Ōmiya andŌita Trinita (1–2).[7]
Ōmiya competed in the J1 League following an immediate promotion in 2015 after being relegated in 2014. Ōmiya was relegated again following the 2017 season. They competed in J12005 and continued to remain until 2014, following promotion from J2 in2004 as the second placed team.
In2023, Ōmiya were relegated toJ3 League after six seasons stint in second division due to worst performance and played third division football for the first time since1993.
On 15 February 2024, before the start of the season, Sports Nippon reported that Austrian energy drink makerRed Bull may buy a J.League club, and that Ōmiya Ardija was the leading candidate.[8] On July 26 of the same year, the Nihon Keizai Shimbun reported that Red Bull had reached an agreement in principle to buy Ōmiya Ardija.[9]
In August 2024, Omiya Ardija announced Red Bull as their new owner, after acquiring 100% of the club shares, formerly owned by NTT, becoming part of their multi-club ownership.[10] This will be the first time that a foreign company has become the sole owner of a major Japanese professional sports team, including the J.League.[11] Red Bull began by acquiring management rights to Austrian first division clubSalzburg in 2005 and now owns six clubs:Leipzig inBundesliga,New York Red Bulls in the United StatesMLS,Liefering inAdmiral 2. Liga,Bragantino inCampeonato Brasileiro Serie A and Red Bull Brasil (nowRed Bull Bragantino II) in the Sao Paulo State Championship. In the past, they also ownedRed Bull Ghana in Africa and Omiya will be the eighth club they own.
NTT East will continue to support the company as a sponsor even after the transfer of shares.[12]
On 13 October 2024, Ōmiya secured promotion to the J2 League after defeatingFukushima United 3–2, thus returning to the second tier after a one year absence. Six days later, Omiya secured the J3 League title with a 1–1 draw againstImabari in matchweek 33.
Their home field is Nack5 Stadium Ōmiya (Nack5スタジアム大宮,Nakku-faibu Sutajiamu Ōmiya):Ōmiya Football Stadium by thenaming rights with occasional games being played at theKumagaya Athletic Stadium.
Ōmiya Ardija has two squirrels as its mascots, named Ardi and Miya. Both wear the team kits. According to the club website, Miya is one size smaller than Ardi, being then, slightly shorter than him.[13][4]
