Irony of Shimao ("ufo in kushiro")
Shimao is a young, reasonably attractive woman in her twenties (despite moles beneath her earlobes). When Komura goes to Kushiro to deliver the package to Keiko Sasaki, he and Shimao end up alone together in a "love hotel." Komura has separated from his wife and wants to feel emotions again, so the two attempt to have sex. Ironically, it doesn't work, despite the circumstances; Komura just can't find the part of himself that he has lost.
Irony of "Landscape with Flatiron"
Miyake is a middle-aged painter living on his own. He tells Junko about a painting he has completed, which he calls "Landscape with Flatiron." It's a picture of an iron in the middle of a room. Miyake says that there's probably some kind of meaning to be found in the painting, but he doesn't know what it is, which is ironic because he's the one who painted it.
Irony of the Obstetrician ("all god's children can dance")
Yoshiya's mother took all the precautions for contraceptives possible, and yet she still ends up pregnant multiple times. Eventually she begins to sleep with her obstetrician, who ensures that all necessary precautions are taken. Despite this, she still becomes pregnant, which is ironic considering that she's been sleeping with an obstetrician.
Irony of Mr. Tabata ("all god's children can dance")
Mr. Tabata, Yoshiya's "guide" in his mother's religion, confesses to Yoshiya that he's had lustful thoughts directed toward Yoshiya's mother, despite his religion. This confession is ironic because Yoshiya himself has had incestuously lustful thoughts toward his own mother - Mr. Tabata's sin seems minor (and understandable) in comparison.
Irony of Takatsuki ("honey pie")
Junpei stood by and watched while his friend Takatsuki courted and married his longtime crush, Sayoto, as the three of them walked through life together. Ironically, Takatsuki, who won Sayoto, walked away from her in favor of some other girlfriend, an action which Junpei could never understand. Junpei stepped in to fill the void left by Takatsuki, taking his rightful place by the side of his love, but ironically acting as father to another man's child.
