until 1871, it was illegal to eat beef in japan.
yeah, you read that right. in fact, it was generally frowned upon to eat any kind of meat taken from livestock until the midst of the meiji restoration. chicken, pork, beef, you name it. while the reason for such an edict is obviously up for debate, many historians think that it was originally put in place to prevent famine. raising large livestock, particularly cows, requires an excessive amount of land and feed which can be put to better use on humans. put simply, beef wasn’t efficient.
