title: Twin database of the secondary school attached to the Faculty of Education of the University of Tokyo.
abstract: This article profiles the historical twin databases of the secondary education school attached to the Faculty of Education at the University of Tokyo. The school was established in 1948. Every year, about 50 pairs of twins of all sex and zygosity combinations and aged 11 to 12 years take an examination, and about 10 to 20 pairs are admitted based on the results. Three independent datasets exist: one for applicants (11-12 years), one for students (12-18 years), and one for graduates (18-72 years). These three historical databases and research perspectives are introduced herein.
