Parceiro Nagano

Foundation and early development (1990–2013)

The history of the club dates back to 1990 when a group of local high school graduates started a football club Nagano Elza SC. The team colours, orange and dark blue, represent Nagano Prefecture, and the team logo uses a lioness named Elza.

In 2007, the club changed the name to AC Nagano Parceiro because the name "Elza" had already been trademarked. However, the club decided to keep the team colors and logo.

In 2011, the team's first season in the JFL, they finished in the second place, but the team was not qualified to for J2 League. J. League Associate Membership status was not granted because the capacity of their stadium did not satisfy the league's requirement (minimum 10,000 seats).

In 2014, the team became the member of the newly founded J3 league, and later acquired the J. League Associate Membership in September as their stadium capacity met the required minimum number of seats.

Establishment in J3 and promotion ambitions (2014–present)

Since joining the J3 League in 2014, AC Nagano Parceiro has consistently aimed for promotion to higher divisions. The club has often finished in competitive positions within the league, though promotion to the J2 League has remained elusive.

AC Nagano Parceiro has built a reputation for its organized style of play and strong defensive performances. The club has also placed emphasis on youth development and community engagement, strengthening its presence in Nagano Prefecture.

In addition to its men's team, the club is notable for its successful women's side, which has competed at the top level of Japanese women's football and achieved domestic success.

In recent years, AC Nagano Parceiro continues to push for promotion while maintaining its identity as a community-focused club representing Nagano.
