Convert Ichitaro documents (JTD) online for free
The converter easily converts your JTD documents to various formats - free and online. No Ichitaro or or other Text software needed.
To convert other file formats to the "Word Processor Document" file type, you need software like Ichitaro or a similar tool.
The .JTD file is a proprietary word processing document created by Ichitaro, a highly popular Japanese word processor developed by JustSystems. These files are primarily used in Japanese corporate, legal, and government sectors to draft documents that require complex Japanese typography, such as vertical text alignment, ruby characters (furigana), and precise manuscript grids.
The official and most reliable software to open a .JTD file is Ichitaro. Windows users can also view these files using the free Ichitaro Viewer or open them in Microsoft Word by installing a specific add-in provided by JustSystems. Under the hood, .JTD utilizes the Microsoft Compound File Binary Format (OLE Structured Storage), which wraps text, formatting data, and embedded images into a single container.
Users frequently need to convert .JTD files because the format is a massive roadblock for international collaboration. Outside of Japan, the .JTD format is essentially unsupported. It requires specific, localized software to open, is not natively supported by macOS, Linux, or web browsers, and halts cross-border workflows when shared with international partners who standardly use Microsoft Office or Google Workspace.
The best conversion targets for .JTD files are DOCX (for continued editing) and PDF (for strict layout preservation). Converting to PDF is highly recommended if the document contains intricate Japanese formatting, as standard word processors may break vertical layouts or custom grids during conversion. If you only need the raw data, extracting to a plain text TXT file is a safe, lightweight option.
The .JTD format is incredibly difficult to convert accurately outside of the original software ecosystem because its rendering engine handles typography differently than western word processors. Standard online converters often fail to process it entirely. However, just drag and drop your file to convert.guru to identify the format, view it, and convert it when possible. Because the file uses OLE structured storage, our analysis can often bypass the proprietary wrapper to extract readable text, embedded media, or identify underlying data structures even without the original JustSystems software.
Use Convert.Guru to open and convert your JTD file.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JTD converter.
