My mother had been asking me for advice on money for her retirement. And recently, she was finally able to start indexing.
In Japan, there is a system called "Tsumitate NISA" that allows investment profits to be tax-exempt for 20 years.
You can only invest up to 400,000 yen per year, but the risk is low and it is good for beginners.

I am happy to be able to show my filial piety to my mother while she is still alive. I would like to continue to help her with asset management.
