Japanese Course Promotion Slide

Goal: Create a Japanese webinar/lesson announcement slide in a cute, simple “Marcy-style” presentation design for Claude Code slide creation course.

Canvas: 16:9 horizontal slide, 1200×675 px, warm cream-peach background with soft abstract circular blobs in pale peach and off-white. Add a thin coral-red rectangular border inset about 20 px from the edge.

Layout: Center-left text-heavy composition with a simple mascot illustration on the right. At the top center, place a wide coral-red folded ribbon banner with angled darker red folded ends. Below it, stack the main headline and subheadline. Place three circular badges in a row under the subheadline. Along the bottom, add one large rounded coral-red call-to-action bar spanning almost the full width.

Text content: Use Japanese text exactly as follows. Top ribbon text: 失敗しない始め方がわかる！. Small centered heading below ribbon: 初心者のための. Large main title in coral-red with white outline/drop shadow: Claude Code スライド作成講座. Teal rounded label below title: AI資料づくりを効率化する方法を解説します！. Three badge labels, exactly 3 badges from left to right: 「参加無料」, 「実演つき」, 「初心者OK」. Bottom CTA text: 「詳しくはこちら！」 in large bold white letters. Add a white circular play button at the right end of the CTA bar with a small coral-red triangle inside.

Subject details: On the right side, draw one minimalist female presenter mascot with a round face, closed eyes, simple smile, short dark-brown bob hair, peach outline, and a white body. Her right arm is raised diagonally holding a small circular pointer. In front of her torso, place one pale blue rounded rectangle laptop/tablet with teal outline.

Decorative elements: Add exactly 4 thin coral plus signs: one near the upper-left edge, one near the upper-right area, one near the lower-left area above the CTA, and one near the lower-right area. Scatter many tiny coral and white dots across the background like confetti, keeping them subtle and not text-like.

Visual style: Flat vector illustration, soft pastel colors, clean Japanese slide design, friendly educational seminar aesthetic. Coral red, teal, cream, gold, and dark brown palette. Use bold rounded sans-serif Japanese typography. Keep all text crisp and centered/aligned like a polished promotional slide.

Constraints: Include exactly 3 circular badges, exactly 1 mascot, exactly 1 CTA bar, exactly 1 play icon, and exactly 4 plus-sign decorations. Do not add logos, watermarks, extra characters, extra badges, QR codes, or additional text.
