Several profiles for Kafū Nagai

[Ema]

I've tried to merge authors by myself when I was sure that I did right. This time I'm not 100% sure which name/profile to choose as the main one. Wikipedia says it's Kafū Nagai, but should I always trust what Wikipedia says?
These are the profiles:

http://www.goodreads.com/author/show/...
http://www.goodreads.com/author/show/...
http://www.goodreads.com/author/show/...

and a damaged one:
http://www.goodreads.com/author/show/...

Please explain how you chose the profile to keep!

Got this one all cleaned up. I also merged the damaged author which occurred because the importer that brought that book in couldn't handle the Japanese characters. Wikipedia is usually OK, as long as you make sure that the info has something to back it up and isn't clearly wrong.

Wikipedia is usually correct when it comes to transliterating foreign language names into English characters. I usually go with it.

If you do merge them all into an incorrect name the work is NOT lost. The name can be changed to the correct one at any time.

Id' rather have 1 profile without the special characters, than 4 different profiles.
