Note: There is no official "portable" version of the Hiragino typeface released by SCREEN (the foundry). In typography and design communities, "portable" usually refers to: 1) A self-contained font file (.ttf/.otf) that can be used across devices without installation (e.g., via suitcase apps or embedding), or 2) The practicality of using the heaviest weight (W9) for digital reading on portable devices (laptops/tablets).
