Rajio no jikan

[Silvia Groniewicz]

Hello!

A few years ago this movie was released in cinemas around Austria and
Germany. I loved the movie and waited ages for a VHS or a TV screening with
subtitles. About two months ago the movie was finally shown on a swiss TV
channel and I was able to get a copy for myself.
My question is not that much about the movie: I'd like to know if the play
that the movie is based on is available somewhere in print. I checked
Amazon Japan, but no luck there. Does is have another title? I was unable
to find anything on the internet except for references to the movie. Any
help would be appreciated!
Thanks,
Silvia Groniewicz

P.S. This is my first posting. I have been lurking for a week already and
this is what I will mostly do since I don't know too much about Japanese
movies but would like to learn a bit about them :)
