How to change font size of Japanese only, in a long document containing both Japanese and English

I have a long Word 2010 document containing both Japanese (MS PGothic) and English (Arial). I tried to set them up initially to be different sizes but Word would not do that. But the Japanese font is simply too hard to read, so I need to somehow change (enlarge) the font size of Japanese only, I have tried search & replace, being sure to specify Asian text and the MS PGothic font. Word simply changes (enlarges) ALL font sizes (including Arial) regardless. Is there a solution for this, or I am I asking for the impossible?

Use different styles to format your English text and Japanese text.

These can include the following attributes:

  • Proofing language
  • Typeface/font
  • Size
