It was taboo to eat steamed rice soaked in Miso soup in coal miner’s society.
While this was a well-known habit of many Japanese households,

construction workers hated this style of breakfast even more than coal miners.
Not knowing this tradition, some new miners were almost beaten to death by other senior colleagues for taking breakfast in such way.
Sakubei assumes the reason why they detested it so badly was that the sight of the rice piled up in soup resembled a burial ground.
