In 1940, amid war in China and growing tensions with the United States, Japan celebrated the 26th centennial of the founding of the Empire of Japan and the "unbroken" imperial line.

This was a carefully choreographed commemoration, one aimed at stoking nationalism, devotion to the emperor and support for imperial expansion. It was an assertion of modern identity couched in crafted traditions and myths, one that evoked a powerful public endorsement evident in various enthusiastic expressions ranging from volunteer work brigades to dutiful pilgrimages to sacred sites.

The celebrations were also aimed at shoring up national morale as the death toll from war against China had reached 100,000. Invoking the virtues of the Yamato race and continuous imperial rule promoted stoic perseverance in the face of adversity, rendering sacrifice a patriotic duty. Little did anyone imagine that only five years later the glorious Empire would collapse in ignominious defeat.
