A color lithograph patriotic fan sample print, likely created between 1937 and 1941 during the Second Sino-Japanese War (1937-1945), depicting two older children in martial poses. A large red star above them bears the inscription 精忠満腹日本魂 日本刀寒一條水 (With unwavering loyalty and a heart full of Yamato spirit. In the cold steel of Japanese swords, like a swift-flowing river.) This saying is taken from a poem, an ode to his grandfather, by Murata Minejirō (1857-1945), historian and author, included in his 1927 history of Bungo and Chikuzen Provinces, about the arrival of Commodore Perry's Black Ships, reading in part (in lose translation):
How audacious these foreign emissaries are!
Their words lack humility, they should be beheaded.
Beating drums, they try to boost their morale,
Sagami Tarō is my master, my sword cuts through the air.
With unwavering loyalty and a heart full of Yamato spirit,
In the cold steel of Japanese swords, like a swift-flowing river,
They vow to sever the heads of these intruders,
In this land of true men among men.
 The Second Sino-Japanese War is referred to in China as the "War of Resistance Against Japan."
 An alias of Hōjō Tokimune (1251-1284) who led the Japanese forces of the Kamakura shogunate against the invasion of the Mongols in 1274.
