Japanese Ad Concept Grid — 4-Panel Poster Layout Prompt

Create a 2x2 grid of stylized Japanese advertising posters across tech, beauty, beverage, and travel industries for marketing mood boards. 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 layout. 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.
