From December 1927, conscripts who had completed a course of study with the requisite marks at a government-run Young Men's Training Institute ("Seinen Kunrenshou"), the curriculum of which included 200 hours of military training, could have their period of active service reduced to 18 months. Normal-school graduates with the requisite marks had their active service reduced to five months. Graduates of middle and higher schools who had completed courses in military training with the requisite marks were required to serve one year for middle-school graduates or for 10 months for higher-school graduates.
Salaries, benefits and pensions
Salaries and pensions for Imperial soldiers and sailors were very low by Western standards. On the eve of the Second World War, the yen had a value of $0.23. No true exchange rate existed for the yen during the war years, and wartime inflation reduced the yen to a fraction of its pre-war value.
