Takeuchi Naoko Sensei no Oheya
Takeuchi Naoko's Room
The Official site of Takeuchi-sensei. It includes new pictures, information, and contact information. It's updated at the beginning of every month (In Japan.. compensate for time diference). However, it's only in Japanese. Your browser must be Japanese enabled to view the site.

Naoko-hime to Yoshihiro-ouji no bebui Punch!!
Princess Naoko and Prince's Yoshihiro's Baby Punch!!
Japanese Only. You can get a report on the contents of the manga.. but it's only in Japanese. ^_^ That's where I found out about Petit Ouji, before it was posted.

Takeuchi Naoko-sensei intavuu
Takeuchi Naoko-sensei Interview
It's partially in English, but mostly Japanese. It's basically a guy interviewing Takeuchi-sensei and some friends. He mainly focuses on her interest in Astronomy. Her editor, Osabu also answers some questions (and is pictured on the main page).

Pages from the Round 2 of Naoko-hime to Yoshihiro-ouji no Baby Punch!! Also connected to a great Sera Myu page.

http://www.geocities.com/Tokyo/Garden/3113/latest.htm
Has reports in English about the latest from Nakayoshi. Usefulk.. it's where Pretty mecha Princess was reported (Now called Toki*Meka).

BLACK MOON- Naoko Takeuchi, creator of Sailormoon
An Alternative to SOS's reporting of the convention (and a better one at that). It lists all the questions in a concise order and with answers. It also gives a first hand report of the convention, rather than second hand report. Plus it reports, rather than feeding opinions to the reader, to give a chance to draw your own conclusions.
The main page also has a lot of neat and interesting information on Japanese culture.

An Interview in English from an Italian Magazine.

An Interesting Essay on Takeuchi-sensei. The main page is also very interesting, though many of the links are out of date.

An Indespensable survey with Takeuchi-sensei translated from a magazine (Brazilian, so the original would be in Portuguese, I think)!

Sailor Moon Uncensored: Anti-SOS
I refuse to list SOS, BTW. They get, "We hate Takeuchi Naoko except when it's not convient award". Please read this link instead. (The main page is also very good)

Ce n'est pas dommage. The info is basic and routine, but well composed. A bit out of date.

http://www.universosailor.8k.com/NaokoBio.html
A Website in Spanish about Takeuchi-sensei. The information looks good. Plus it has a picture I don't have. (It's from the 80's pre-Sailormoon.)
