Dynamic Japan Soccer Poster

Create a dynamic vertical sports poster with a distinctive Japanese football graphic design style. Canvas: 2:3 aspect ratio, off-white paper background with a slight grainy texture. Subject: A black-and-white illustration-style football player wearing a Japanese national team jersey; jersey number:{argument name="jersey number" default="10"} The scene depicts the moment of kicking a ball, with one leg extended towards the audience, featuring dramatic ink-wash shadows, tousled black hair, and a face with soft gray square blurring. A black and white soccer ball with perspective is added in the lower left foreground, appearing to fly outwards. Behind the player, a large, bold black letter is placed.{argument name="main letter" default="J"} With a white outline and red offset shadow, it partially obscures a large red sun centered behind the athlete. Explosive abstract geometric shapes surround the figure: diagonal blue speed bars, red and black stripes, yellow accent lines, detailed engineering lines, halftone dot clusters, small square pixels, ink blots, and angular fragments radiating from the lower left to the upper right. A limited color scheme of black, white, deep royal blue, bright red, and a small amount of yellow accents is used. The composition should have the feel of a modern Japanese football promotional poster—high contrast, vibrant, urban, and printable. A small date is included in the lower right corner.{argument name="date text" default="May 15, 2026"} Above it is a handwritten signature.{argument name="signature" default="Oyagi"} No additional logo, no additional players, no other readable text required.
