A similar but less stringent path was set out for those enlisted into the primary or secondary reserve categories; they would also end their service on the national service list. The least rigorous path was for those enlisted into the hoju hei-eki (replenishment territorial army and naval volunteer reserve), who would end their service on the national service list.
In peace-time, Class II recruits were not recruited, but were assigned to national service. In wartime, Class II B-1 and Class II B-2 recruits were enrolled into the hoju hei-eki category, with II B-1 recruits enlisted into the first supplementary territorial army and naval volunteer reserve and II B-2 recruits enlisted into the second supplementary territorial army and naval volunteer reserve, respectively. II B-1 recruits would serve for two years and four months in the territorial army or one year in the naval volunteer reserve; II B-2 recruits would serve for 12 years and four months in the territorial army or 11 years and four months in the naval volunteer reserve. Upon reaching the age of 40 in peace-time, all soldiers in Classes I and II would be placed on the national service list and released from regular duties.
In practice, total conscription of the available population was only instituted during the Second World War. Before then, only a proportion of the secondary reserve service had been called to active duty, during the Russo-Japanese War. Class III-C recruits were automatically assigned to national service if necessary. Conscripts classified as Class IV-D were reexamined the following year; if they could not be reclassified into any of the first three classes, they were officially exempted from all military service. Sole supporters of families and criminals sentenced to over six years penal servitude were automatically listed as Class IV-D and exempted from all service. Students at certain higher secondary schools were classified as Class V-E until they had finished their studies or upon reaching the age of 27, whichever came first. Japanese students studying abroad were also classed as Class V-E until reaching the age of 37.
