How to Stop Word from Changing Font to MS Mincho for Japanese Text
Question details
The user needs a way to prevent Microsoft Word from automatically switching the selected font to MS Mincho when typing with the Japanese Microsoft IME.

- Product
- Microsoft Word (Microsoft 365)
- Device & OS
- Windows
- Scenario
- Switching to the Japanese Microsoft IME to input text while using a specific font like DengXian.
- Observed behavior
- Word automatically forces the font to change to MS Mincho upon switching to the Japanese IME, overriding the user's selected font across multiple computers.
Verify if your preferred font (such as DengXian) fully supports Japanese Hiragana and Katakana characters, as missing glyphs often trigger Word to use an automatic fallback font.
Update Microsoft 365 to the Latest Version
Installing the newest updates can resolve known Microsoft IME and formatting compatibility bugs within Microsoft Word.
Microsoft occasionally releases updates to patch known issues involving the Microsoft Japanese IME and Word's text formatting behavior. Ensuring your Office suite is up to date is the primary troubleshooting step for this specific bug.
Launch Microsoft Word, click on 'File' in the top-left corner, and select 'Account' from the bottom of the left-hand menu.
Under the Product Information section, click on the 'Update Options' drop-down button.
Select 'Update Now' from the menu. Wait for Microsoft 365 to check for and install any available updates, then restart Word to see if the font issue is resolved.

Report the Font Behavior via Windows Feedback Hub
If the issue persists across multiple updated devices, it is likely a software bug that needs to be reported directly to Microsoft for a future patch.
Manually Modify the Asian Text Font Settings
Manually setting the Asian text font in your Word document can sometimes override the automatic MS Mincho substitution.

Frequently Asked Questions
Why does Word automatically change my font to MS Mincho?
Word relies on MS Mincho as a default fallback font for Japanese text. If your currently selected font lacks Japanese characters, or if there is a known compatibility bug with the Windows IME, Word will automatically apply MS Mincho to ensure the text renders correctly.
Can I set a different default font for Japanese text in Word?
Yes. You can press Ctrl+D to open the Font dialog box, select your desired font under 'Asian text font', and click 'Set As Default'. This tells Word which font to prioritize when typing in Asian languages.
Does the DengXian font fully support Japanese input?
DengXian is primarily optimized for Simplified Chinese. While it shares many CJK ideographs (Kanji) with Japanese, it may lack comprehensive Kana support. This missing support often causes Word to fall back to a dedicated Japanese font like MS Mincho.
