I recall reading somewhere about a common practice to make a supplementary ¥400 contribution towards one’s monthly pension deductions.
I’m not 100% aware of the specific benefit (aside from the general contribution pool being increased) and why it’s set at ¥400 precisely.
I’m also wondering if the ¥400 deduction can be added onto one’s workplace payroll deductions for a dependent spouse?
If it’s beneficial, how is that arranged?
Thank you.
