I would like to propose name convension about Japanese emperor. My new convention is simply: 

{era name or given name} emperor 

1.TABThere is no ambiguous name basically so putting "of Japan" is redundant. 
2.TABMy world history book uses this notation, which seems conventional. Google attests too. 
3.TABFor example, because meiji is an era name not ruler name so it is sometimes misleading to say Emperor Meiji of Japan, which sounds Meiji is a name of ruler just like other monarcy in westerns. 
Any objection?  Taku 17:10 Mar 8, 2003 (UTC) 

I will compile this conversation regarding the title of Japanese emperors. If there is no much objection, I will rename the titles in days.   01:51 Mar 9, 2003 (UTC)
