Seeking advice for a friend who has a PR and hasn't informed the Japanese financial institutions about leaving the country.
They have moved formally out of Japan. They have never told banks, brokerages, exchanges, etc about that.
They claim they used those financial institutions to the minimum like paying for bills for their property in Japan. And brokerages & exchanges they haven't used as non-resident.
However, they might have been providing misleading information to those institutions to avoid account closures while non-resident.
They are aware this is wrong but don't know the penalties and consequences? And if they have to do something to rectify their missteps?
EDIT: added questionmakrs, edited for clarity.
