Tübingen University, Dōshisha University, and Korea University decided in 2015 to strengthen the ties between the three universities by facilitating academic exchange and by organizing annual workshops and conferences.

With TUCKU, Tuebingen University's center in Korea, and TCJS, Tuebingen University's center in Japan, the triangle network is closely interconnected.

For the period of 2017-18, TuDoKu was supported by the PaJaKo-Program of the DAAD with the title "Transnational Cultures: Korea, Japan, and Germany".

For the period of 2019-21, TuDoKu is supported by the GEnKO-Program of the DAAD with the title "Everyday History in Korean Studies".
