Japan Institute of Constitutional Law

Hōgakukan Kenpō Kenkyūjo

Aiming for constitutional research and promotion of the constitution, the Japan Institute of Constitutional Law (法学館憲法研究所) was founded in 2002 by Makoto Itō, a lawyer and the founder of a cramming school for the national bar examination, Itō-juku (伊藤塾).

The institute's website is very large and contains an online database of numerous books and theses regarding constitutions. On their website, the institute also introduces a series of articles explaining constitution-related issues for junior and senior high school students, as well as a large amount of constitution-related movements, articles, events, court judgments, and movies.

In 2015, Itō published a statement to call for cancellation of the security bills, collecting signatures on the institute’s website.
