One of the recent studies of posthumanity in Japanese SF is typified in the 2013 publication Posuto hyūmanitīzu: Itō Keikaku igo no SF [ポストヒューマニティー：伊藤計劃以後のSF, Posthumanities: SF after Author Itoh Project], including a variety of discussions of “Japanese-style” posthumanity by a group of young male critics called Genkai-ken (限界研, Studies of the Limit). In “The Preface” of the work critic Fujita Naoya summarizes the concept of “Japanese-style posthuman” from the articles by contrasting it with ideas of posthumanity in Europe and the U.S. Japanese-style posthumanity is epitomized in four respects: 1. There are “very few” euphoric depictions of humanity (humanity eternally develops toward the singularity, or humanity has achieved immortality by eternal soul-copies or resurrection); 2. Japanese-style posthuman tends to be oriented toward subjects who are infused with or plugged into the Social Network System (SNS), the communication system, or ‘the air’; 3. The relationship between the self and the character has been merged based on the character platform culture in Japan (perhaps due to influence of Buddhism and animism); 4. Komatsu Sakyō’s (小松左京) works Hateshinaki nagare no hate ni (果しなき流れの果に, End of the World after Endless Streams, 1966), “Kami heno nagai michi” (神への長い道, A Long Path to the God, 1967) and Kyomu kairō (虚無回廊, Empty Corridors 1987, 2000) influenced the concept. The focus on posthumanity is about the boundaries of humanity and human bodies, permeation and diffusion, and liminality (See details in the book).
Women writers such as Ueda Sayuri (上田早夕里, b.1964-) also employ science fiction rhetoric to undo human and to undo gender expectations in the world around them. In other words, science fiction gives them freedom from the constraints in actual societies. In reconfiguring the human, these women seek alternative worlds with alternative entities such as cyborgs and non-humans, alternative sex/gender and sexualities, and alternative relationships, which problematize or deflect a hierarchal patriarchy, binaristic gender, and a heteronormative system. In particular, their use of cyborg and posthuman models as metaphors―in keeping with Donna Haraway’s concept―is a tool for reconfiguring human forms through science and advanced technology.
From a larger perspective of humanity, Ueda Sayuri offers a new form of ecocriticism and ecofeminism in SF to challenge our human gender system. To illustrate, Ueda’s series of novels known as the Ocean Chronicles (Karyū no miya 華竜の宮, 2010; Shinku no hibun 深紅の碑文, 2013) offers a “queer” angle of perceiving the human through various posthuman subjects. She creates a highly imaginative world populated by genetically engineered sea people who live on the margins of society. The world they inhabit comes into being after a drastic environmental change. Here they interact with fish-boat-like creatures and with autosapients.
