Japanese companies are warming to mobilizing their mountains of accumulated cash for mergers and acquisitions but remain stubbornly resistant to wage increases, a poll showed on Monday.

Prime Minister Shinzo Abe's government has struggled for years to coax companies to lift wages, seen as the missing link for a sustainable growth cycle led by consumer spending. But deep-seated doubts stirred in part by the nation's shrinking population have left firms loath to take on higher fixed costs.

Instead, they have hoarded their cash or, increasingly, begun looking to overseas acquisitions as a way to escape the limitations in their home markets.
