A god appearing at a shrine proves its presence, but leaves open why it deserves worship, whether its demands are just, and who may speak in its absence. Power can compel obedience without earning devotion; a blessing can reward a bargain without endorsing a priesthood. Nor does one god’s testimony settle the claims of another, especially where their interests conflict. Temples and rulers must still turn encounters into doctrines, favours into precedents, and particular acts into lasting authority—each step offering room for ambition, misunderstanding and fraud. The sacred becomes a demonstrable presence, while the legitimacy claimed through it remains thoroughly contestable.
A daimyō sits at the centre of a network of households, land rights and obligations. His power depends on people who collect his revenues, hold his castles and bring armed followers when summoned.
Seven houses shape northern Iga, gathering lesser warrior families around mountain holds, cultivated valleys and guarded roads. Their authority rests upon overlapping claims: inherited land, military service, marriage, shrine patronage and agreements between neighbours. No house commands enough men or wealth to dispense with the others. Their children grow up across these boundaries, sometimes as spouses, sometimes as wards whose continued residence guarantees peace.
Banking in Iga operates through merchant houses, moneylenders and trusted associates. They provide credit, arrange payments and convert goods into spendable wealth. Borrowing bridges the interval between expenditure and income, allowing households, workshops and warrior families to meet obligations before their revenues arrive.
For Iga around 1580, travel depends upon local authority, the purpose of the journey and who can vouch for the traveller. There is no single passport that guarantees passage throughout Japan. The more systematic Tokugawa network of permits and checkpoints belongs to the later Edo period.
