Kilvert attempted to be as true to the era as possible and strove to depict historical authenticity within the context of the story. "The most difficult thing we had to do in designing this film was to find a way to honor the rules of Japanese architecture while finding ways to make them photographable," she says. "Much of it is very precisely designed. The
length of a tatami mat and the height of a shoji screen are specific measurements. In the end, we had to break some of their specifications. In general, I tried to assemble the essential elements and create an authentic feeling of a particular time."
