Wow, I'm amazed that something like this has survived. I rescued it from among the items haphazardly piled up during the rebuilding of my family's warehouse. My mother passed away about 13 years ago at the age of 81 from dementia caused by a subarachnoid hemorrhage. I boarded with my uncle's family in Kawasaki, where they lived, and attended a domestic science school. After graduating, as the war situation worsened, my grandfather went to Kawasaki to bring her back. Immediately after, she worked at the village office, which had lost its male workforce. After the war, she married my father, who was a civil servant, and there was a time when she was asked by the parents of young women before they got married to teach them dressmaking. She even made suits, which were quite demanding, because she couldn't refuse the requests. Looking at the textbooks with interest, I can't help but hope that this kind of item will find its way into the hands of someone who is researching them and survive.
