The Takarazuka is an all-female theatrical revue famed for its splendor and its otakuyaku -- women playing male roles, offstage as well as on.
More theory than history. Focused on the immediate pre- and post-war years; not much sense of the current Takarazuka. Despite Robertson's claims that femininity is as learned as a masquerade as masculinity (which I believe), she mostly focuses on the otakuyaku instead of the musumeyaku.
The pictures are great. The androgynous otakuyaku are seriously hot.
