When it was opened, there were fields along Omiya-dori Street heading east from the Kansai Main Line, Japanese National Railways (current JR), but once Shin-Omiya Station opened along the Kintetsu Nara Line, the neighborhood developed into a new city, and as the city hall was relocated from the former city, offices, business facilities, and department stores began to develop.
開通当初は、国鉄（現JR）関西本線以西の大宮通り沿いは田畑が広がる田園地帯であった（いくつか集落はあった）が、近鉄奈良線に新大宮駅が開業すると、付近は新都心として発展し、市役所が旧市街より移転するとその傾向に拍車がかかり、オフィスや商業施設、百貨店などが林立することとなった。
