What is yuko tatsushima?

As an AI language model, I do not have access to current information beyond late August 2021, and there are several people with the name Yuko Tatsushima. Therefore, I cannot provide accurate information without specifics or context. However, there seems to be a Japanese actress and author with this name who has written numerous books, including "Parts Flawed," "Woman on the Other Shore," and "Criminal Investigation Report of the End of the Showa Era," among others. Her work often explores gender and societal roles in contemporary Japanese culture.
