In the process of bringing Mario to
America, many of the names of the characters were changed. I have found
a Japanese site with the names of most of the characters from the NES
Mario games. Listed here are the English names of main Mario characters,
their Japanese counterparts, and how to write their name in Japanese. If
you want to check out the site where I found this info, click here.
Make sure you have Japanese text support on your browser to see the
Japanese text. Enjoy.
