Upon its English-language release, ("Tokyo Sympathy Tower") was described by David Vernon writing in The Spectator as 'a lyrical, witty, satirical but meditative and meticulous text', one that 'feels so über-zeitgeisty that it might have been written this morning ... Yet it is far more than merely topical or trendy, as deep moral, political, social, cultural, architectural and lingual problems collide, merge and inform (on) each other throughout'.
Qudan lives in Chiba Prefecture.
