"Kairyudo Publishing Co. focuses on Wikipedia, the Internet-based free
encyclopedia, in its textbook, discussing how it began and how it is used.
Based on information from Wikipedia, Zoshindo-Jukenkenkyusha Publishing Co.
features in its English textbook a map highlighting countries that maintain
the death penalty.
An Education, Science and Technology Ministry official said: "We just check
whether the descriptions in the textbooks are appropriate after confirming
that they're based on facts. We don't care whether they deal with Wikipedia
or not." "
