Naramura I believe is the name, but that's just a minor thing, and no one really cares about the whole Japanese names.
For Raruga, a little research seems to lead me that all the resources on the Raruga site uses the Creative Commons Attribution of Japan (Similar to what Blizzard uses for Chaos-Project and his scripts). If you are not familiar of it, here is the link:
http://creativecommons.org/licenses/by/2.1/jp/deed.enIf you are even more lazy, I'll just quote it directly.

The Google translation of Naramura states this somewhere in the Game Page:

The copyright of the material itself is uneven. ?????????????????????????????????????????? Otherwise, I would like to make things, unless your game do-it-yourself of your freedom to please.

Seems to me that as long as you credit, you're okay. Crediting includes giving the name of the site or the name. Hope this helps.
