Yosuke Glass

A glass-and-neon theme for Obsidian with a Japanese-first font stack.

• Dark: Future Glass — deep navy ground, frosted-glass panels, cyan / purple / pink neon accents.
• Light: Paper — warm paper ground, white note card, the same accents toned down for reading.
• Japanese typography first — Hiragino Sans (macOS / iOS) → Yu Gothic (Windows) → Noto Sans CJK (Android) so bold headings render properly in Japanese. Latin falls back to Inter / system fonts. No fonts are downloaded; nothing leaves your device.
• Written to be maintainable — variables first, Obsidian's --color-base-* ladder for both modes, one feature per section, edit view and reading view always styled as a pair, and zero !important.

Companion plugin

Yosuke Design (companion plugin, not yet published) is the settings panel for this theme: light/dark palettes, typography, Nick Milo–style folder color bands, custom fonts from your vault, and a design.md file you can hand to any AI to restyle your vault. The theme works on its own; the plugin requires the theme.

Install

Settings → Appearance → Themes → Manage → search Yosuke Glass.

Manual: copy manifest.json and theme.css into .obsidian/themes/Yosuke Glass/ and select the theme.

Structure of theme.css

1. body { } — variables only (palette, neon colors, fonts, sizes, radii)
2. .theme-dark / .theme-light — the --color-base-00…100 ladder and accent HSL
3. Per-feature styling, only where variables cannot reach (each block styles edit view and reading view together)
4. Third-party plugin overrides (isolated at the end)
