Ok i stand corrected as you say the OP stated certain criteria.

Although even within these criteria exceptions still apply

Sakoku (鎖国, "locked country") 1633- 1850 ish.

Many hardships were faced but as with the OP's criteria lets look at food

Tenmei Famine
Tenpo Famine

to name just 2.

Now this is hardley unique as many countries in the world suffered famines tho I dare say an argument could be made that if Japan was not in a period of isolation things may have turned out different.

Again im just playing "devils advocate"
