Eisai Juku (英才塾; Cram School for the Gifted) was a cram school which appeared in episode 80 of the Sailor Moon anime. The school served as one of the Negative Points that the Black Moon Clan needed to use as part of their plan to contaminate twentieth-century Tokyo with Dark Power.
After Esmeraude placed the Dark Henge at the school and set her Droid, Giwaku, to guard it, the students of the school began to act in a strange fashion and began to spread rumors that Ami Mizuno only got such good grades because she was cheating. After she realized that, Ami went to the school herself to investigate and discovered the Black Moon Clan's presence.
- In the first English dub the school was called "Albert Einstein School for the Gifted."
