Adobe Keeps Translation foreign fonts to english???

You need to make sure your system has Japanese support. Then you would type characters using an Input Method Editor.

Or, once there is Japanese support in the system, you can use copy and paste from other apps.

You do NOT need to download a font, and free fonts aren't likely to be good quality. Because of the tens of thousands of characters in them, good Japanese fonts can cost thousands of dollars. However, both Adobe software, and the Windows and Mac systems come with excellent quality Japanese fonts ready for use.

All Japanese fonts include English as one of the four commonly used alphabets.
