From the text:

The rayon man, a Mr. Matsui, had opened his then unoccupied estate to a large number of his friends and acquaintances, so that they might evacuate whatever they wished to a safe distance from the probable target area. Mr. Tanimoto had had no difficulty in moving chairs, hymnals, Bibles, altar gear, and church records by pushcart himself, but the organ console and an upright piano required some aid. A friend of his named Matsuo had, the day before, helped him get the piano out to Koi; in return, he had promised this day to assist Mr. Matsuo in hauling out a daughter’s belongings. That is why he had risen so early.

Hersey discusses how the Jpanese people feel about the ethics of using the bomb to end the war.How do Mrs.Nakamura and Dr. Sasaki feel about this?
