Tokyo Seven Roses' is set in Japan during the waning months of WWII and the beginning of the Occupation. It is written as a diary kept from April 1945 to April 1946 by Shinsuke Yamanaka, a fifty-three-year-old fan-maker living in Nezu, part of Tokyo's shitamachi (old-town) district. After the war, Shinsuke learns by chance that the Occupation forces are plotting a nefarious scheme: in order to cut Japan off from its dreadful past, they intend to see that the language is written henceforth using the alphabet. To fight off this unheard-of threat to the integrity of Japanese culture, seven beautiful women - the Seven Roses - take a stand.
