Dark Echo Grounds
→ This site hasn't been updated for over 2 years, but it is a timeless classic. I'm sure you've at least heard of it before - its the "elite" Sailor Jupiter Shrine - tons of info, insightful articles, great descriptions... you get the point. Honestly, you could spend a few days digesting all of the information held here. The summary? Visit this site.

Evolution
→ Another famous Sailor Jupiter Shrine. It has lots of information, articles and cute sections such as real-life Makotos, how to dress up as Sailor Jupiter and more.

Jeweled FantaZies
→ This is a nice site with information about Sailor Jupiter's life (past, present and future), fanfics, multimedia and games. Worth a visit.

Sailor Jupiter's Home
→ Alright, this site has some basic information on Sailor Jupiter plus a page on the differences between the anime and manga character. It used to have a cute "funny faces gallery", but all of the images are broken. Other than that, it's a decent site.

Thunder Angel
→ This is a great site. There is a lot of in-depth information about Makoto, even some about her parents (yes, the ones that died in a plane crash before the series began). Curious? Visit the site, it's worth the time.
