Kangaroo Notebook (カンガルー・ノート, Kangarū Nōto) is a novel written by the Japanese writer Kōbō Abe between ca.

One morning, while pondering the stress of his latest assignment at his uninspiring job, the narrator of Kangaroo Notebook feels an itching on his leg that seems to indicate an unusual hair loss.

After battling to be seen in his local medical clinic, he enters a hospital, where a physician prescribes hot-spring therapy in Hell Valley.

Hooked to a penile catheter and an IV bottle, the narrator begins a harrowing journey on his hospital bed through the underworld that seems to lie beneath the city streets.

Here he seeks, not so much health, as simple explanations for what is happening to him and the strange people he meets: abusive ferrymen, waif-like demons, vampire nurses, and a chiropractor who runs a karate school and has a side job carrying out euthanasia procedures.
