Question details
The user needs to change the application interface language of Adobe Acrobat 11 Pro to Japanese.

- Product
- Adobe Acrobat 11 Pro
- Device & OS
- not provided
- Scenario
- The user wants to navigate menus, read tools, or edit PDF documents using a Japanese user interface in their installed Acrobat 11 Pro software.
- Observed behavior
- The current interface language is set to a non-Japanese language, requiring the user to either switch the language in the preferences or install the missing Japanese language pack.
Ensure you have administrator privileges on your computer and access to your original Adobe Acrobat 11 Pro installation files, as adding a new language might require modifying the core installation.
Change the Language via Acrobat Preferences
Use this method if the Japanese language pack was already included and installed during your initial setup of Adobe Acrobat 11 Pro.
Acrobat 11 Pro allows you to switch between installed interface languages directly from the application's Preferences menu.
Launch Adobe Acrobat 11 Pro, click on 'Edit' in the top menu bar, and select 'Preferences' from the dropdown list.
In the left-hand sidebar of the Preferences window, scroll down and click on the 'Language' category.
Under the 'Application Language' section, select 'Choose at application startup' or directly choose 'Japanese' from the dropdown menu, then click 'OK'.
Close and reopen Adobe Acrobat 11 Pro to apply the new Japanese interface language.

Modify the Installation to Add the Japanese Language Pack
Use this method if the Japanese language option is missing from the Preferences menu, meaning it was not installed initially.
Easily Manage PDFs in Multiple Languages with WPS Office
Avoid complex software modifications and large language pack downloads. WPS Office features a built-in, lightweight PDF reader and editor that makes it incredibly easy to switch your entire interface to Japanese in just a few clicks.
- 1. Download WPS Office: Download and install the free WPS Office suite from the official website.
- 2. Access Global Settings: Launch WPS Office, click on the Settings gear icon located in the upper right corner of the home screen, and select 'Settings'.
- 3. Switch the Language: Navigate to 'Language', select 'Japanese' from the list of available languages, and click the confirmation button to set it as default.
- 4. Restart the App: Restart WPS Office. The software, including the WPS PDF tools, will now display completely in Japanese.

Frequently Asked Questions
Why is Japanese missing from my Acrobat 11 Pro language options?
During the initial installation of Adobe Acrobat 11 Pro, specific language packs are often deselected by default to save storage space. You must modify the installation via the Control Panel to add Japanese.
Do I need to purchase a new license to change the language in Acrobat?
No, changing the interface language or adding a language pack through the installer's modify option does not require a new license, provided your current edition supports multi-language installations.
Will changing the interface language translate the text inside my PDF?
No. Changing the application language only updates the software menus, toolbars, and settings. It does not automatically translate the actual text content of your PDF documents.
Does WPS PDF support editing Japanese documents?
Yes, WPS PDF fully supports reading, editing, and annotating documents in Japanese. You can also easily switch the entire WPS Office interface to Japanese from the settings menu.
