Japan’s Government Pension Investment Fund (GPIF), the largest pension fund in the world, is looking at Bitcoin ( BTC ) as a potential diversification tool.

The GPIF officially announced on March 19 the development of new long-term investment policies in response to “major changes in the economy and society, and rapid technological progress.”

In response to the new challenges, the GPIF is launching a five-year research plan to explore innovative methods to diversify investments with an emphasis on sustainability and risk management.

As part of the plan, the GPIF will request various data, including information about “illiquid assets” that the company does not currently hold. Such assets include cryptocurrencies like Bitcoin, precious metals like gold and other assets, the announcement notes.

This is a developing story, and further information will be added as it becomes available.
