The Japanese Flag Sign or J-Flag is a vertical floor-standing banner commonly used as a shopfront advertising sign and for promotions in walkways or shopping malls. Its structure features a single side pole with top and bottom bars to keep the banner sheet stretched, making it highly visible, clear, and wind-resistant — ideal for businesses that need fast and effective communication in limited spaces.

  • Originates from Japan where vertical flag-style banners are widely used outside shops, resembling “customer-attracting flags.”
