Plugin to change language of PDI

[GaominZ]

Is there any free usable plugin that can be used to change the system language of PDI?

If there is, how can I install it?
(I want to change the language to Japanese)

I've alraeady check the [Activate Plugin] on servicenow|developer page and could not find it.

HI @GaominZ ,

You will need to install the following plugins :

1>I18N: Internationalization
com.glide.i18n
2>I18N: Knowledge Management Internationalization
com.glideapp.knowledge.i18n2
3>Localization Framework Installer
com.glide.localization_framework.installer

4>I18N: Japanese Translations

com.snc.i18n.japanese

Thank you very much for the kind reply!
May I ask where can I find the install page for PDI?
Here's how I;ve tried:

1) Go to home page of ServiceNow Developer
2) click the account icon 
3) select "Activate Plugin"

and that's the page I reached. Yet I could not find the plugins you suggest above by searching. 
Would you mind sharing the correct way of setting? Thank you !

Hi, Thank you sooo much for the details. I successfully set up my PDI with Japanese!
Please kindly allow me ask one more last question:

I installed the 4 plugins you sussegsted above.
Yet I found that the fourth one, "I18N: Japanese Translations"(com.snc.i18n.japanese),  seems to included the other 3 plugins inside?
Is it OK if I only installed  "I18N: Japanese Translations"?
Or I must installed all of the four plugins you listsed up ?

Again thank you for your help and am looking foward you could help me with this last question!
