Japanese 2x2 Banner Grid: Customizable 4-Theme Ad Prompt

Generate a stunning Japanese-style 2x2 banner ad grid with customizable themes: skincare, travel, food, and finance. Perfect for multi-campaign promotions. Use it as a Art Conceptuel starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type and quadrants. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
