Japan's Economy and Fiscal Policy Minister Nobuteru Ishihara expressed concern about uncertainties of the global economy and the impact on the real economy, following the British pound's plunge and a drop in the Japanese share prices. 
"The pound's steep fall and the declining Japanese stock prices reflect that the markets are paying a close attention to uncertainties about the global economy," he told reporters on Tuesday. 
"It is important to analyze how such uncertainties will affect the real economy," Ishihara said. 
He made remarks as the pound has plunged against the dollar and the euro on ongoing concern over Britain's exit from the European Union. 
In the Tokyo stock market, an intraday price fell below the psychologically important 19,000 mark in the morning for the first time since December 30.
