Japoński Baner Reklamowy SaaS

A polished square Japanese digital advertising banner for an AI e-commerce optimization tool, split into two visual zones by a bold diagonal blue divider line running from upper-center to lower-center-left. On the left third, a realistic nighttime home-office scene shows a tired young woman sitting at a desk, her face intentionally blurred, resting her head on one hand while looking at an open laptop. Warm desk-lamp lighting illuminates her and the desk, with a mug in the foreground, scattered papers, and out-of-focus shelves and a wall clock in the dark background, conveying late-night overtime. On the right two-thirds, a deep blue gradient promotional panel features faint financial-growth charts in the background, topped by bold oversized Japanese headline text in white with strong drop shadow stacked across four lines: "[深夜の\nサムネ入れ替え、\nもう自動化\nできます。]". Beneath it, a white subheadline with a thin cyan underline reads "[楽天専用 A/Bテスト自動化ツール]". Below that, a horizontal process strip displays three white rounded-corner cards connected by two cyan right-pointing arrows: Card 1 shows two handbag thumbnails labeled "サムネA" and "サムネB" with "VS" and percentage badges "64.3%" and "35.7%"; Card 2 shows a selected black handbag thumbnail with a small gold crown, checklist lines, and a turquoise checkmark badge indicating automated optimization; Card 3 displays an analytics chart with bar graphics, a pink trend line, and a pink result metric "+47.2%". At the bottom left, a bright pink rounded promotional badge reads "[1週間\n無料トライアル]" in bold white text. At the bottom right, a dark navy rounded logo bar displays a white geometric emblem and brand name "[Easy Creative]". Clean modern SaaS-ad aesthetic, high contrast, crisp typography, glossy UI cards, 1:1 aspect ratio.
