Create a 16:9 explanatory slide in [Slide Format] format about [Theme]. Fuse a gentle, friendly Japanese public-information illustration atmosphere with the overwhelming information density of Japanese bureaucratic presentation slides. Use a cream background, rounded simple characters, soft flat colors, cute icons, arrows, section boxes, numbered modules, small data tables, process flows, role summaries, mission/objective blocks, outcomes, lessons learned, and tiny annotations. Make the slide feel approachable at first glance but extremely information-rich on closer inspection. Use Japanese text labels where appropriate, with clear hierarchy: large title at top, subtitle, multiple numbered sections, diagrams and icons in the center, dense summary blocks along the bottom. Keep the composition organized, humorous, educational, and presentation-ready. Avoid copying any specific illustrator or stock-asset brand style exactly, real logos, private information, official government seals, misleading factual claims, extra watermarks, unreadable microtext, overlapping boxes, broken arrows, distorted characters, and low-resolution artifacts.
