The Japanese financial landscape is undergoing a significant transition as the country moves from a zero-interest rate environment toward positive interest rates. Long-term interest rates have surpassed the 3% threshold, driven by expectations of further hikes by the Bank of Japan. This shift is reflected in the mortgage market, where Flat 35 rates for terms of 21 years or longer have risen to 3.26%, and major banks like Mitsubishi UFJ and Sumitomo Mitsui have increased both fixed and floating rate products due to rising procurement costs.

While 75% of mortgage borrowers continue to utilize variable interest rate plans, a slight shift toward fixed-rate options is emerging. Anxiety remains high, with 47.2% of respondents expressing uncertainty regarding how repayment amounts change when rates rise. Many borrowers remain unfamiliar with the ‘5-year rule’ and the ‘125% rule,’ which are mechanisms used to cap monthly payment increases in variable-rate, equal installment repayments.

Rising construction costs have also driven approximately 38.7% of borrowers to use pair loans or income aggregation to increase borrowing capacity—a figure rising to nearly 60% among those in their 20s. Experts warn of risks such as potential income loss during maternity leave, divorce, or death.

In response to the changing environment, the financial sector is adjusting strategies. Life insurance companies are promoting savings-type products to leverage higher interest rates for increased future payouts, while major banks are intensifying efforts to attract deposits to expand lending capacity and improve interest margins.
