Account

口座 ／ bank-account　—　Institutions

A record of money deposited in a bank. The balance figure is a debt the bank owes to you.

Banknotes in a wallet are a liability of the central bank; an account balance is a liability of a commercial bank. ⚠ Even for the same 10,000 yen, what protects it in the event of a failure changes depending on whose liability it is.
