The depreciation of the Japanese yen is generating significant commercial advantages for the nation's multinational corporations, leading many to revise their profit projections upwards during the latest earnings season.

Despite recent intervention efforts by the Japanese government, market expectations indicate that the yen will continue to face downward pressure. As a result, companies with substantial overseas exposure, including Toyota Motor, Honda Motor, Sony, and Ryohin Keikaku Co Ltd, the parent company of Muji, have all upgraded their earnings outlooks.

According to a report from Okasan Securities, among the approximately 1,600 constituent companies of the TOPIX index, 159 have raised their full-year earnings forecasts since July 1, while only 12 have lowered their projections. The overall ratio of earnings forecast revisions stands at 86%, marking the highest level since the 2016 fiscal year.
