Before we dissect the "W9 Verified" tag, we must understand the source.

Hiragino (柊野) is a family of sans-serif and serif typefaces designed by Jiyuko Kobayashi and produced by SCREEN/ADK (formerly known as "Dainippon Screen"). It has been a cornerstone of the Apple ecosystem since Mac OS X 10.3 (Panther), later becoming the default Japanese system font for macOS and iOS.

Unlike Western fonts that have "Bold" or "Black," Hiragino operates on a numeric weight scale (W0 through W9).

For Windows or Linux users, you must purchase the formal package from SCREEN. The package titled "Hiragino Sans Ｖ６" includes all weights from W2 to W9.

| Platform | Installed by default? | How to access W9 | |----------|----------------------|------------------| | macOS 10.14+ | Yes | Any app supporting system fonts | | iOS / iPadOS | Yes | UIFont with name HiraginoSans-W9 | | Windows | No | Requires purchase or font embedding | | Linux | No | Not available (use Noto Sans CJK JP Black) | | Web (CJK) | Only on Apple devices | Falls back to synthetic bold or Noto |

⚠️ Licensing note: Hiragino fonts on macOS/iOS are licensed for use on those devices only. Do not extract and redistribute .ttf/.otf files for web embedding unless you purchase a separate web font license from SCREEN.

In app design, Hiragino W9 is reserved for the highest severity alerts. For example, a count badge on a notification icon (e.g., "99+") uses W9 to ensure the tiny numerals remain solid and don't break down due to sub-pixel rendering.

The keyword "Verified" is critical. It implies three distinct things depending on who you are:

✅ Verification note: Apple’s system font list confirms Hiragino Sans W9 as a discrete font file, not a synthetic bold of W6 or W8.
