“[. . .] Rediscovering the Vision of Science Fiction. We cannot call everything with a monster in it science fiction, but if we make the presence of a hypothesis our standard, then we are free to widen the field considerably. The evolutionary line of science fiction could include not only Karel Čapek’s R.U.R.  and War with the Newts , but even Franz Kafka’s Metamorphosis  and David Garnett’s Lady into Fox . We could broaden our definition endlessly, going beyond the commonly accepted idea of the ‘science fiction writer’ to include authors like Mark Twain, Robert Louis Stevenson, August Strindberg, Guillaume Apollinaire, Vladmir Mayakovsky, Jules Supervielle, Lu Xun, Sōseki Natsume, Uchida Hyakken, Akutagawa Ryûnosuke, Ishikawa Jun, and so on.
“And we could go even further back, to Swift, Cervantes, Shakespeare, Dante, Apuleius, and Lucian. The pedigree for our literature of hypothesis would eventually trace itself all the way back to the Greeks.
“Viewed in this light, science fiction’s vision is not a narrow branch within literature but part of the mainstream, a literary current far longer and deeper than a movement like Naturalism, for example. Even if this vision does not encompass all of literature, it is a part too important to leave out. And if there is a potential for a boom in science fiction in our country, it will be a great blessing for Japanese literature, afflicted as it is with a shortage of hypotheses.
