Japanese ClaudeCode Training Banner

Create a clean corporate Japanese web banner for an AI training service, wide horizontal format around 1200x247. Use a bright white and pale blue office aesthetic with a modern professional business look. The layout has 5 clear text/icon areas plus one human figure on the right. On the left, place a small top tagline in Japanese reading 「AIはじめてでも安心。実践で身につく。」 in medium blue-gray, aligned near the upper left with a subtle dotted accent mark to its far left. Below it, place a very large bold headline in deep blue reading 「ClaudeCode研修" with the Latin word oversized and the Japanese word continuing on the same line. Under the headline, place 3 evenly spaced rounded white feature boxes with thin blue borders and blue line icons. Box 1 contains an open book icon and the Japanese text 「基礎から丁寧に学べる」. Box 2 contains a laptop icon and the Japanese text 「ハンズオンで実践力がつく」. Box 3 contains a checkmark in a circle icon and the Japanese text 「チーム開発に活かせる知識」. Along the entire bottom, add a full-width deep blue bar with centered white Japanese text 「あなたの開発を、次のステージへ。". On the right side, show 1 professional Japanese businessman from the waist up, wearing a dark navy or black suit, white shirt, and blue striped tie, arms crossed, facing forward with a confident posture; his face is intentionally blurred or anonymized. Behind him, use a softly blurred modern office interior with bright daylight, glass, and green plants. Add a sweeping curved blue accent ribbon along the far right edge framing the subject. Overall style: premium B2B seminar ad, polished typography, soft gradients, minimal clutter, strong hierarchy, high readability, Japanese enterprise branding, subtle shadows, crisp vector icons, and balanced negative space.
