List of Familial Terms
Using Familial Terms To Address Strangers
If you're about the same age, you can address strangers with brother and sister terms: Oniisan and Oneesan. It's not too different from going "Hey, bro."
If the person you're address is much older, you can call them uncle or aunty: Ojisan or Obasan.
If the person is really old, then you can call them grandfather or grandmother: Ojiisan or Obaasan.
