This plugin adds reading guides, known as furigana, to Japanese kanji characters directly within the site editor. It is designed for content creators, educators, and site owners who publish Japanese text and need to make it accessible to learners or readers unfamiliar with complex kanji.

• One-click furigana addition: Select Japanese text in a paragraph or heading block and click a single button in the toolbar to apply accurate furigana.
• Client-side morphological analysis: The plugin uses the Kuromoji library to analyze text directly in the browser, ensuring fast operation without sending data to a server.
• Standard HTML output: It generates proper <ruby>, <rt>, and <rp> HTML tags, which are widely supported by browsers and maintain semantic correctness.
• Toggle functionality: You can click the same button again to remove the furigana from the selected text, allowing for easy editing and correction.
• Performance caching: Analyzed results are cached locally to speed up repeated operations on the same text within an editing session.
