What is the author's style in A Personal Matter by Kenzaburo Oe?

The story is told from the third person, past tense point of view. Its perspectives are defined and/or limited to the perceptions and reactions of protagonist Bird. Narration is omniscient (all knowing), but only when it comes to Bird's experiences. The actions, intentions and feelings of the other characters are seen, interpreted, and understood through the filter of his perceptions and history. This brings the reader closely and intimately into Bird's situation, although it's important to note that many readers might find being put in such a position uncomfortable, given some of what Bird experiences.
