Yahoo! Japan ad sizes & safe zones

All 7 Yahoo! Japan ad formats (4 image, 3 video), grouped by placement category — the same specs the resizer exports.

Safe-zone values are pixels (top / bottom / left / right) at the format's native recommended resolution — keep text, logos, and CTAs out of those margins so platform UI doesn't cover them. Formats without a value have no platform-documented safe zone.
