Create an original square Japanese shopping coupon board in red, yellow, navy, and white, with two angled coupon tickets and clear price hierarchy.
Text: “まとめ買いクーポン”, “8% OFF COUPON”, “4% OFF COUPON”, “期間限定”.
Use a clean retail-promotion layout with only two small highlight stars.
Keep all visible text in Japanese or the original English coupon words. No brand, watermark, QR code, website, Chinese text, or random tiny text.
