The psychosexual landscape of Japan—the land of tentacle porn, a galaxy of erotic video games, hikikomori shut-ins, and recent anxiety over teenage asexuality—has been a fount of fascination for the rest of the world. The hallucinatory plays of former psychiatrist Kuro Tanino have been described by Japanese critics as a "queasy" kaleidoscope into those national obsessions and desires. Tanino favors phalluses, obsessive students, women wearing pig and sheep masks, dwarves, ejaculating trees, and disjointed story lines packed into tight and claustrophobic sets. The Room should be a strange trip. (On the Boards, 100 W Roy St, ontheboards.org, 8 and 10 pm, $25, Feb 6–9)
