Twenty-nine-year-old Riki is sick of her dead-end job, of struggling to get by ever since she moved to Tokyo from the country. So when someone offers her the chance to become a surrogate in return for a life-changing amount of money, it's hard to turn down. But how much of herself will she be forced to give away?

Retired ballet star Motoi and his wife, Yuko, have spent years trying to conceive. As Yuko begins to make peace with her childlessness, Motoi grows increasingly desperate for a child to whom he can pass on his elite genes. Their last resort is surrogacy; a business transaction, plain and simple. But as they try to exert ever more control over Riki, their contract with her starts to slip through their fingers . . .

He decides to chase it and, like Alice pursuing the White Rabbit, he tumbles down a hole, out of the human world and into the realm of the Kappas. There he is well looked after, in fact almost made a pet of: as a human, he is a novelty. He makes friends and spends his time learning about their world, exploring the seemingly ridiculous ways of the Kappa, but noting many—not always flattering—parallels to Japanese mores regarding morality, legal justice, economics, and sex. Alas, when the patient eventually returns to the human world, he becomes disgusted by humanity and, like Gulliver missing the Houyhnhnms, he begins to pine for his old friends the Kappas, rather as if he has been forced to take leave of Toad of Toad Hall…
