We adress the shortage of people in uniform with absurd high pay, a private gets 2000€ before taxes plus money for every day and every kilometer he is from home in his base.Japanese military suffers from the unholy combination of
- Military being a low respect and low pay occupation
- Literally dwindling number of young people
- No conscription
This problem is the same with Germany's. This is among the primary reasons why you hear them "getting themselves armed again" annually yet no drastic change in force compositions happen. As far as I can remember, articles about Japanese and German remilitarization (I find this term funny considering their existing spendings) were common in even ~2012. Yet the progress was just incremental. No serious change happened. In 2022 both increased their budgets substantially but I don't expect anything drastic. Most of the new budgets will go to increased salaries to keep enough people enlisted.
Lieutenants (basically 21 year olds when starting right after high school) get almost 3k€ base after taxes plus the aforementioned subsidees regarding away from home.
And it still doesnt work because half of those people you attract are money hungry greeds and not really fit for service.
