Ocean Wave Creative Inspiration

Create an original square Japanese summer coupon poster in orange, cream, and warm yellow, with a bold central discount panel and compact date strip. Text: “夏のお買い物応援フェア”, “最大20% 割引クーポン”, “期間限定 2026.08.01-2026.08.18”. Use only subtle sunburst lines and two small sparkle accents. Keep all visible text in Japanese. No brand, watermark, QR code, website, English text, Chinese text, or random tiny text.

Use case: product-mockup. Reference image: minimalist beach color gradient only. Create a clean vertical 2:3 tranquil summer beach background: a broad powder-blue sky fading gently lighter toward the horizon, a subtly blurred turquoise sea band at mid height, and fine pale warm sand across the lower third with soft natural ripple texture. Keep the center open and uncluttered for product placement. Photorealistic yet softly dreamy coastal editorial style. Change horizon softness, sand ripple pattern, sky gradient, and reflection details so it is related but not identical. No text, numbers, Chinese characters, watermark, brand logo, tiny edge text, border, white margin, or corner mark.
