On a warm November morning last month, I was in the grandstands for the Japanese Eastern Command’s Parade of the Eastern Army. As the seats around me slowly filled before the performance, I noticed a pair of young men in puffy down jackets on the tarmac below. Peering more closely, I could make out the action figure of a female heroine from an anime series between them. One of the young men took a photograph of the toy and, apparently satisfied with his framing of the mini-skirted cartoon girl against the backdrop of military vehicles, returned the figure to his companion’s satchel and then mounted the stands.
