If you find a font that will display the Kanji character set, you can add that font to the cmd Settings by adding values under this Registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont\
Values:
Name: 00
Data: Consolas
I’ve done this before but found this reference on SuperUser: https://superuser.com/q/55318
Hope this helps
