I collected these names from a site listing family names in Japan. Someone listed the site on http://forum.koohii.com/ but I haven't been able to find it. Lucky at the time I found the link, I created a text file. I finally decided to upload it to anki and start using it personally for learning names.
(This is for recognition but can be changed around to reverse if needed, thanks to anki)
(Deck contains over 8000+ names)
I'll be posting another deck(separate from this one). Containing common names plus names from coscom and lastly Wikipedia(all the names on there will be in that deck). The deck will contain both male/female full names.
