Users can easily format their text using familiar syntax seen on popular Japanese novel websites. The plugin provides a user-friendly interface that allows you to edit your documents while previewing the ruby markings in real time. Commands like novel-ruby-insert and novel-ruby-remove streamline the process of adding and removing ruby marks. With support for both English and Japanese interfaces, this plugin enhances your writing experience in Obsidian, making it an invaluable tool for writers and readers alike.

The kkh plugin for Obsidian allows users to convert text between old and new styles of Japanese kana and kanji. It offers six types of transformations, including converting from modern to traditional kana, traditional to modern kana, modern to traditional kanji, and traditional to modern kanji. The plugin also supports conversions for combined styles like modern kana and kanji to traditional equivalents and vice versa. Users can select text in the editor and apply transformations through the ribbon menu, command palette, or text menu, with support for macOS, iOS, iPadOS, and Android. This plugin streamlines the process of switching between different versions of Japanese writing, making it a valuable tool for linguists, historians, and anyone working with older Japanese texts or modernizing traditional content.

The Jisage Formatter plugin for Obsidian helps users display text with full-width spaces at the beginning of lines, commonly known as "Jisage," correctly within their notes. This formatting style is especially useful for languages like Japanese, where proper indentation can be critical for readability and aesthetics. By installing this plugin, users can ensure that their notes maintain the intended structure, including correct indentation in reading mode. However, users should be aware that changes to full-width spaces may not immediately reflect in reading mode due to an Obsidian app limitation—reopening the file resolves this issue. This plugin is perfect for anyone working with text that requires precise formatting for languages or styles that use full-width characters for indentation.

The Furigana plugin for Obsidian adds functionality for marking selected text with ruby annotations, allowing users to display furigana readings for kanji. This is particularly useful for learners of Japanese, as it provides immediate access to pronunciation guides directly within Obsidian. The plugin enables users to highlight text and apply the `<ruby>` HTML tag to show furigana readings. Currently, the plugin is focused on this annotation feature, with plans to add automatic kanji-to-hiragana conversion in future updates.

The Markdown Furigana plugin enhances the readability of multilingual text in Obsidian by rendering furigana annotations, commonly used in Japanese and other languages. By applying a simple markdown syntax, users can display kanji, kana, or other scripts with pronunciation or transliteration aids, improving comprehension and accessibility. The plugin processes furigana rendering during preview mode without altering the original notes, ensuring clean and flexible note editing. It supports multiple furigana sections, allowing detailed annotations for complex scripts, making it particularly useful for language learners or those working with annotated text.
