More Japanese companies now report that rising interest rates will hurt their business, a significant shift from the past decade. This growing concern complicates the Bank of Japan's delicate task of normalizing policy after years of near-zero borrowing costs. The survey highlights a new vulnerability for corporate Japan.

The shift comes as the central bank gradually exits its ultra-loose monetary stance, a move that has kept borrowing costs exceptionally low. For many firms, especially those with high debt, higher rates threaten to squeeze profit margins and deter investment. This creates a direct conflict between policy goals and corporate health.

Investors will watch how this sentiment affects earnings forecasts and capital expenditure plans. The Bank of Japan must balance its inflation-fighting mandate against potential economic drag. Any sustained negative impact could force a slower pace of rate hikes, influencing bond yields and the yen's value.
