Wikia uses MediaWiki be excellent at Category and Template functions as Wiki software.

The reasons why I found Japanese TESWiki are:

  • It seems that it is difficult to create Japanese version (interwiki links) of UESP Wiki caused by this discussion.
  • The existing Japanese Skyrim Wiki, Oblivion Wiki, Morrowind Wiki and so fourth are individually founded. But Japanese version of one wiki integrated these wikis do not exist.
  • The existing Elderscrolls-related wikis do not use MediaWiki. Thus these wikis can not use "Template:", "Category:" and so forth.
