Seijun Suzuki's portrayal of Taijiro Tamura's, "Shunpu den" articulates Tamura's philosophical notion that "nikutai koto ha subete da" (the body is all there is). Harumi attempts to flee the despair of her situation as a comfort woman in Manchuria by rejecting the ideological and the transcendental; notions that bind her future lover Mikami. Mikami, a solider for the Imperial Japanese army, despite his love of philosophy and ideas (in a time when outside thought was strictly forbidden), is bound by nationalistic virtues of honor and duty; virtues essential to the foundation of the Imperial Japanese ideologies kokutai (national polity) and tennosei (the emperor system).
Harumi, who wants to, "throw herself against as many bodies as possible", finds that she can only know others through the physical sensations of the body: physical pleasure, touch, and sex. Although she falls in love with Mikami, she is outraged by his devotion to the Imperial Will, which appears hypocritical. Consequently, this hypocrisy proves fatal for Mikami.
In the spirit of Tamura's philosophy, we are left with the notion that there is no honor in dying; that only in the struggles of life can one derive honor, and that nothing is more important than continuing one's existence.
