Hagoromo
Hagoromo is a macOS Japanese rich text editor for vertical writing, outlining, ruby text, and long-form document editing.
What is Hagoromo?
Hagoromo is a native macOS rich text editor built for Japanese writing and document creation. It is designed for users who need features that go beyond a basic text editor, especially authors, editors, and other people working with vertically written Japanese text. The app supports vertical writing, manuscript paper mode, ruby annotations, tate-chu-yoko, emphasis marks, and outline-based editing for structuring longer documents. It also includes powerful search and replace tools, style-based find and replace, full-screen editing, iCloud document support, automatic saving, versioning, and version comparison. Hagoromo documents are based on RTFD compatibility, so users can still open the underlying content in other compatible Mac editors, although app-specific formatting may not fully carry over. The publisher also notes that sales have stopped and support ended for macOS 26 and later, so it is mainly relevant on older supported macOS versions.

Safety overview
Status: Mostly safe
Hagoromo is a legitimate writing app for macOS and its file access is consistent with creating and editing documents. The main practical concern is compatibility: the publisher states that support has ended for macOS 26 and later, and App Store sales have stopped. If you still use it, keep important documents in standard formats and test your workflow before relying on it for new work on newer systems.
Recommendation: Keep Hagoromo if you actively use its Japanese writing features or need access to older documents created with it. If you no longer use it, removing the app is usually fine, but export or confirm access to any important files first and consider switching ongoing work to a currently supported editor.
