I have some autocad files (dwg) that contains Japanese characters. When i open this
file with AutoCAD 2013, the japanese characters come through as random
numbers,letters and symbols. Other text such as numbers comes through fine.

This may or may not be of some help to you,
What's the version has the dwg file created? I suspect this dwg file is created by ACAD2007 or older version and you saved with ACAD2013. If in this way, the code page has been destroied. You must get the origional dwg file, and use code page convert tool to change the code page, then it could be opened with ACAD2013 with right Japaniese characters.
You could find the code pager convert tool at below link:
That are some problem from my collegue in japan, he send not the DWG drawing but DXF, after he replace with DWGs
those problem was solve.
