For the Japanese ranking I believe this one
https://st.benesse.ne.jp/ninshin/name/2010/name-ranking/ is more conclusive
It's hard to argue which one to include (the reading list or the kanji list) since they're both essential to Japanese names, but the kanji lists are more extensive
Thanks for the website link, it includes rankings going back to 2005 which is really helpful
