A sleek Japanese corporate training banner in a wide horizontal web-ad format. Background is a dark navy-to-deep-blue gradient featuring subtle glowing network nodes and connecting digital lines across the upper and middle sections. On the right side, a confident Asian businessman shown from the waist up with arms crossed, wearing a dark navy suit, crisp white shirt, and blue striped tie, cropped partially at the top and right edges. On the far right, an angled bright cyan polygon callout panel overlays the image with bold dark Japanese text in two lines reading "[明日からの開発が\n変わる体験を。]". On the left, strong typographic hierarchy in clean modern Japanese sans-serif: a small cyan sub-headline at top reading "[AIを活用した開発スキルを、最短で習得]", above an oversized bold white main title reading "[ClaudeCode研修]". Arranged horizontally along the lower-left are three rounded rectangular feature cards outlined in bright cyan with dark translucent fills and cyan icons: box 1 with a terminal code icon and "Claude Codeの基本と応用", box 2 with a rocket icon and "開発スピードを飛躍的に向上", box 3 with a two-person team icon and "現場ですぐに活かせるスキル". Polished commercial marketing aesthetic, high contrast, luminous cyan accents.
