As a special assistant professor in the Department of Civil Engineering, the University of Tokyo, Mr. Hagiwara is participating in Urban Redesign Studies Unit which is providing an education of master course students from department of Civil Engineering, Architecture and Urban Engineering in the University of Tokyo.

In the process of reconstruction after the Great East Japan Earthquake, Mr. Hagiwara conducted research on the reconstruction of fishing villages in Iwate Prefecture that were affected by the tsunami, and contributed to the reconstruction of communities in Minamisoma City, Fukushima Prefecture, where residents were forced to evacuate after the Fukushima nuclear accident.

The Urban Redesign Studies Unit was established after the 2011 Great East Japan Earthquake, as an organization to imagine cities, regions, and land for the next generation. The education program aims to collaborate with various fields other than engineering, to establish new urban society models that can be applicable for each urban, regional, communal, and continental level, and to develop the model into global cities outside of Japan.
