it's reasonable to assume that this represents the amount of rice japan should allocate per-peasant in a functioning economy with other food sources. it would be meaningless and absurd to develop a standard for the amount of rice one would need in a year if and only if rice was the sole food source in their universe. In fact I'd be willing to bet there's no amount of rice that would keep a person alive for a year if that's all they ate.
