Hakodate Minimalist Line Art — Retro Travel Poster Prompt

Generate a sophisticated monochrome line-art poster of Hakodate, Japan, featuring elegant Japanese typography, a detailed street view with trams, and a classic mountain backdrop. Use it as a Arte Conceptual 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, format, style, main text, scene, composition, and instructions. 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.
