Recently, the stock price performance of a major listed company in Japan has been quite explosive. In just the first two trading days of the year, it has surged continuously, with Tuesday's closing price reaching 510 yen. Compared to 405 yen on December 30, the cumulative increase is nearly 26%.

This surge is backed by real support—the company just announced a major move. On December 30, they invested $451 million to acquire 4,279 bitcoins at an average price of $105,412 each. The total holdings now reach 35,102 bitcoins.

Why is this company so aggressive? The key lies in the structural weakness of the Japanese yen. Due to yen depreciation, they have secured lower financing costs. Each coupon is denominated in a relatively depreciated currency, meaning they completed their acquisitions at a lower cost than their American counterparts. From another perspective, the yen's weakness has actually become an advantage for them, increasing the potential returns on their holdings.
