Following the recent performance of the Japanese stock market, Berkshire Hathaway Inc has reportedly increased its holdings in five firms to an average of over 8.5%.
It is well known that the company has stakes in Itochu Corp, Marubeni Corp, Mitsubishi Corp, Mitsui & Co and Sumitomo Corp.
It is understood that its aggregate value now far exceeds the public shares held by Berkshire in any other country outside the United States.
Berkshire plans to increase its investment to 9.9% of each of the five firms and will not make purchases above that level unless approved by the investee's board of directors.
Berkshire chairman Warren Buffett had previously said that he would increase his stake in the Japanese company in April, driving the stock to record highs.
Earlier this year, Buffett and Vice Chairman of non-insurance operations Gregory E. Abel flew to Japan and met with the CEOs of each of the 5 companies.
