工部大学校
Tatsuno studied architecture at the Imperial College of Engineering where he was a student of the influential British architect Josiah Conder, called "father of Japanese modern architecture". After his graduation in 1879, Tatsuno journeyed to London in 1880 attending courses at the University of London. During his stay he worked at the architectural offices of the Gothic Revivalist William Burges. Burges died in 1881 during Tatsuno's stay, but before returning to Japan Tatsuno also took the opportunity to travel extensively in France and Italy.
