Corman hit later established Origin Press, publishing some of these same authors as well as his own works. In the late 1950s he moved to Kyoto, Japan where he found work as a private teacher of English and poetry. He married Shizumi Konishi in 1965 and opened C.C.'s, a coffee and dessert shop that also served as a venue for poetry readings.
