The blood-red sun, a recurring motif in the narrative, weaves its symbolism from the title to the Japanese flag and even to Papa’s boat, the Taiyo Maru (translating to sun circle). This motif, rich in significance, takes on multiple meanings throughout the story.

Primarily, the blood-red sun serves as the emblem of Japan. Its presence in the narrative consistently marks moments where characters grapple with their Japanese heritage. While Grampa proudly displays the symbol, Mama buries it underground. For Tomi, the sight of the blood-red sun on the planes signifies Japan’s attack. As the narrator, Tomi grapples intensely with the symbol. On the one hand, it represents his Japanese roots; on the other, it embodies the unmet expectations he feels burdened by.

Beyond its cultural connotations, the blood-red sun also becomes a poignant symbol of lost innocence. Tomi’s realization, triggered by the symbol on the planes, shatters the illusion of his home’s safety and thrusts America into war.
