expression
fellow soldiers rely on one another; people in the same situation should help each other
Proverb emphasizing mutual aid among those in similar circumstances, originally among warriors.
武士は相身互いというから、困ったときはお互い様だ。
As the saying goes, 'fellow soldiers rely on one another,' so when in trouble, we should help each other.
The phrase originates from the samurai code, where warriors in the same profession were expected to support each other. The exact historical derivation is uncertain.
