The increasing demand for overseas stocks by retail investors in Japan has put additional pressure on the depreciating yenThis growing trend, driven by various factors, reflects a shift in the traditional investment landscape in Japan.
Last year, the Japanese government expanded the scope of its NISA (Nippon Individual Savings Account) system, encouraging individuals to invest more funds into long-term opportunitiesThis initiative not only increased participation among personal investors but also prompted investment trusts to significantly purchase foreign stocks and funds, with investments reaching ¥10.4 trillion (approximately $66 billion), the highest level since 2015. Since the inception of NISA, a noticeable trend of capital flowing towards overseas markets has emerged, with indications suggesting that this trend could intensify by 2025.
Shota Ryu and Daisaku Ueno, currency strategists at Mitsubishi UFJ Morgan Stanley Securities, noted, “In the short term, the selling pressure on the yen driven by NISA may escalate

Moreover, Nomura Securities has pointed out that a significant portion of the rise in the USD/JPY exchange rate last year is attributable to Japanese investors increasing their overseas securities investments through NISA
While NISA accounts also permit investments in domestic assets, the combination of a weak yen and relatively low returns from Japanese assets has limited their attractiveness for Japanese investorsSince NISA’s launch in 2014, returns in the U.Sequity market have more than doubled those of Japan, further contributing to capital flight from Japan and heightening the depreciation pressure on the yen.
However, volatility in overseas markets could impact the scale of capital flows through NISA in 2025. Significant market fluctuations might influence investors’ decision-making processes, potentially alleviating some pressure on the yenConversely, should the Japanese market attract capital inflows due to better yields or strong stock performance, this could offer some support for the yen.
At present, investment flows linked to NISA have prompted the yen's depreciation, driving it down to its lowest point since July 2024. At the beginning of 2025, the eMAXIS Slim U.S
