How to display Japanese fonts in a .txt file i received?

I received an email attachment that is a .txt file.
Some of it is in Japanese and some is in English.
The Japanese text turns out to look like gibberish.... like this...

If i send this cut/paste back to the person who emailed it to me, they say it is displaying fine in Japanese.

I have no idea how to make this text show up in Japanese.
Thanks for any help.
