Introduction: A New Ambition in Saitama
RB Omiya Ardija Ventus is a professional women’s football club based in the city of Saitama. The club was a founding member of Japan’s first fully professional women’s competition, the WE League. While deeply rooted in its community, a recent acquisition has set the stage for a dramatic new era.
The club is now officially known as RB Omiya Ardija Ventus following its integration into the Red Bull global football network. This change signals a new level of ambition for a team defined by its local identity and its intense rivalry with powerhouse Urawa Red Diamonds Ladies. This guide explores the club’s complete history, from its foundational principles to its promising future.
Context: The WE League
Omiya Ardija Ventus competes in the Women Empowerment League, commonly known as the WE League. This is the top tier of women’s professional football in Japan. The league was established in 2021 to elevate the sport’s profile and create new opportunities for female athletes. For a complete overview of the competition, see our WE League Hub.
The Ardija Way: Philosophy and Identity
The club’s identity is built on a strong connection to its local community. The name “Ardija” is derived from the Spanish word ardilla, which means squirrel. The squirrel is the official mascot of Ōmiya Ward and the park where the team’s home stadium is located.
- Club Philosophy: The official mission is “to contribute towards the realisation of a better society where people can share their dreams and passions through sport.”
- Home Stadium: The team plays its home matches at the NACK5 Stadium Ōmiya (Nack-Five Stay-dee-um Oh-mee-yah), a venue with a capacity of 15,500.

Club History: From Foundation to a New Era
The club was officially established in 2021 to compete in the inaugural WE League season. Its origins trace back to the team FC Jumonji Ventus, which competed in the Nadeshiko League Second Division. This team was brought under the Omiya Ardija umbrella to form the new professional entity.
A landmark moment occurred in late 2024. Global company Red Bull GmbH announced its acquisition of the club, making it the first foreign-owned major professional sports team in Japan. Beginning with the 2025 season, the team was renamed RB Omiya Ardija Women. It adopted the signature Red Bull logo while retaining its traditional orange and navy colours, marking a new phase of investment and development.
A Rivalry Forged in Saitama
The club’s most significant fixture is the Saitama derby. This match is played against their crosstown rivals, Urawa Red Diamonds Ladies. The rivalry is one of the most anticipated in the WE League, reflecting a deep-seated local contest that also defines the men’s teams.
However, the results have been historically one-sided. Urawa Reds have dominated the meetings since 2021, highlighting the competitive gap between the established champions and the developing Omiya side. Closing this gap remains a primary goal for the club and its supporters.
Omiya Ardija Ventus Major Honours
As a young club, Omiya Ardija Ventus is still pursuing its first major domestic trophy. The team has been a consistent mid-table competitor in the WE League, with its highest finish being 6th place in the 2022-23 season. Performances in the Empress’s Cup and WE League Cup have been challenging, often resulting in group stage or early-round exits.
