Japanese 2x2 Ad Grid Prompt — Skincare, Food, Travel & Fitness

Create a professional 2x2 grid of Japanese digital advertising banners for multiple industries with customizable headlines and promotional offers. Use it as a コンセプトアート 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, layout, 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.
