ClaudeCode Corporate AI Training Banner

Create a simple Japanese corporate training banner using a wide banner header format with a white background and a deep navy blue brand color. Laid out as a unified AI programming course promotional banner. On the left, a prominent bold Japanese subtitle "AI を使用こなす開発へ" is placed, and below it is a very prominent large heading "ClaudeCode Training", written in bold sans-serif deep navy blue, with "ClaudeCode" font especially large, followed closely by the Japanese word in the same style. Below the title, add a horizontal gradient strip from dark blue to light blue, containing bold white Japanese text: "Development in the AI era, become your weapon.”。 In the lower left corner, three circular navy blue icon badges are arranged horizontally, each with a brief two-line Japanese description to the right. Badge 1 displays the code symbol </>, with the text "Claude Code 基本から實踐まで" (From the Practice). Badge 2 displays a light bulb icon with the text "AI Utilization Skills to Enhance Business Efficiency." Badge 3 shows an upward trend chart, with the text "Ready-to-use practical content." On the right half is a bust of a confident Japanese businessman with crossed arms, dressed in a deep navy blue suit, white shirt, and blue striped tie, facing forward; Her face is either soft-focus or anonymized. Behind him, add layered geometric navy blue with blue slashes swept over from the top right and bottom right, as well as a deep blue tech-themed panel with light code lines and glowing braces {}. Adopts a refined B2B seminar advertising style, with clear layout, ample white space, subtle gradients, high contrast, and a professional AI/engineering training atmosphere.
