Welcome to the not-too-distant future: Japan, having vanished from the face of the earth, is now remembered as “the land of sushi.” Hiruko, its former citizen and a climate refugee herself, has a job teaching immigrant children in Denmark with her invented language Panska (Pan-Scandinavian): “homemade language. no country to stay in. three countries I experienced. insufficient space in brain. so made new language. homemade language.”

As she searches for anyone who can still speak her mother tongue, Hiruko soon makes new friends. Her troupe travels to France, encountering an umami cooking competition; a dead whale; an ultra-nationalist named Breivik; unrequited love; Kakuzo robots; red herrings; uranium; an Andalusian matador. Episodic and mesmerizing scenes flash vividly along, and soon they’re all next off to Stockholm.
