Prefecture this week: Saitama Prefecture!
NACK5 Stadium Omiya is a football stadium located in Ōmiya-ku, Saitama City, Saitama Prefecture. Built in 1960, it was originally name as Omiya Football Stadium but in 14 May 2007, it was renamed for sponsorship purposes as part of a long term agreement. It is now a home stadium for “Omiya Ardija”, a soccer club which plays in J League Division 1 in Japan.
The stadium used to accommodate 12,500 spectators. It was expanded to the current 15,500 spectators but because they need to fund the renovation, the city of Saitama opted to sell the naming rights and thus, the reason of the renamed.
This is the oldest football-specific stadium in Japan. In the past, it host several matches of 1964 Summer Olympics and 1967 National Sports Festival of Japan.
A fun fact about the stadium is that this is the venue for the High School National Championships on the soccer manga-anime “Captain Tsubasa”
