In 1937, the Shinmin no michi (The Way of the Subjects) was given to all Japanese citizens in order to teach them how they should behave. Similarly, the Japanese war ministry issued the Senjinkun (Field Service Code) in 1941, which tried to educate the soldiers on how to behave during wartime. Specifically, the Senjinkun contained the famous ideal of no-surrender which inspired many Japanese servicemen to commit suicide than risk capture or surrender.[113] Observation of civilian wartime diaries and letters suggest that the government was successful in garnering massive support for the war.
