Japanese stocks saw a significant influx of foreign funds into the week through April 4, a turnaround from three weeks of selling. Foreign investors invested a net of $18.65 billion into Japanese stocks, reversing nearly two-thirds of the 4.45 trillion yen withdrawals the previous week. Factors such as seasonal shifts from Tokyo to offshore entities and rising Japanese government bond yields also contributed to foreign inflows. However, foreign investors remained net sellers for a fourth consecutive week.
