Officials say people with "Flat 35" and other housing loans handled by the agency may be entitled to interest rate reductions and mortgage forbearance.
The agency will also offer low-interest loans for home repairs and reconstruction.
Under a plan open to applications this month, affected residents who wish to build a new home can borrow up to 37 million yen for land and housing or up to 27 million yen for housing alone, at a fixed annual interest rate of 1.59 percent.
Applicants who apply to buy a new, existing house or condominium can borrow a maximum of 37 million yen, or up to 12 million yen to repair a current home, at the same interest rate.
In all cases, applicants will require a disaster victim certificate from their local government to qualify.
