勘 means 'intuition'

This bundle examines financial culture in the Edo period (1603–1867). Because most Japanese couldn't save much, they honored frugality, embracing the sayings "Bear noble poverty, despise riches" and "A man is still a man even if he's poor." Money was tight even for many provincial lords, who halved samurai salaries. But some folks did have money; they bought things on credit, paying off debts at year's end, and whatever the Edo native earned by day, he famously spent at night on drinking and prostitutes. Garments in which people stored cash gave rise to a term for "financial standing."
