Activist investors in Japan have poured an estimated 890 billion yen ($6.06 billion) into Japanese stocks in the first half of this year, building on last year's record. The two most active activists are Farallon Capital Management and 3D Investment Partners, with Farallon investing in Astellas Pharma and T&D Holdings. Rising activist clout has led to a record 14.6 trillion yen in share buybacks and potential changes to Japan's corporate landscape, including a management buyout plan announced this year.
Activist investors are increasingly focusing on Japanese stocks, with an estimated 890 billion yen ($6.06 billion) invested in the first half of this year, according to data from Bloomberg. This figure surpasses last year's record and reflects growing confidence in Japan's corporate governance reforms and shareholder-friendly shifts [2].The two most active investors during this period are Farallon Capital Management and 3D Investment Partners. Farallon has invested in Astellas Pharma Inc. and insurer T&D Holdings, while 3D Investment has made a significant wager on Square Enix Holdings Co. [2].
The surge in activism is leading to a record 14.6 trillion yen in share buybacks this year, up 8% from the first nine months of 2024. This increase in share buybacks is a direct result of the growing influence of activist investors, who are pushing companies to return cash to shareholders [2].
The rising clout of activist investors is also reshaping Japan's corporate landscape. There have been 24 management buyout plans announced this year, surpassing the 19 announced in 2024. Additionally, there have been 88 takeover bids so far, surpassing the record 87 bids from last year. These deals are helping to prop up Japanese share prices, as fresh cash is injected into the market [2].
The trend of activist investors targeting Japanese stocks is likely to continue, driven by the country's improving corporate governance and increasing institutional interest. As more companies adopt shareholder-friendly policies and improve their operational efficiency, the opportunities for activist investors to drive value creation are likely to increase.
