I was going by the article, which says this:

> Applicants will also be required to have a pension pot equivalent to 30 years of payouts.

If there's a better article to read, I'd appreciate a link.

> Draft Revisions to the Guidelines for Permission for Permanent Residence (Summary)

...

> Regarding the positioning of the "Permanent Resident" status of residence:

> ・ Explicitly stated for the first time that, as it is "the most stable legal status—entailing no restrictions on activities or duration of stay and presupposing a lifetime spent in Japan"—there is a "need for particularly careful screening."

...

> Regarding "2. Requirement for Independent Livelihood"

> ・ Underlying Principle: Explicitly requires an economic status equal to or better than that of Japanese nationals, both currently and in the future.

> ・ Income: Whether income consistently meets or exceeds the average income level of Japanese households based on household size (raising the standard).

> ・ Pension: Whether the projected future pension benefit amount reaches the level corresponding to 30 years of enrollment in the Employees' Pension Insurance at the aforementioned annual income level (newly added requirement; however, financial assets that can cover any shortfall will also be taken into account).
