Tokyo - Tokyo stocks opened lower on Tuesday with exporters hit as the yen jumped on US and European political uncertainty.
The Japanese currency, which often draws safe-haven buying in times of instability, rose on questions over US policy implementation under President Donald Trump and concerns about the French election.
"The market's tone has been one of risk-off, as political fallout in both Europe and the United States is weighing on investor resolve, imposing an unpalatable risk on investor sentiment," said Stephen Innes, senior trader at forex firm OANDA.
"Investors are now seeking shelter in safe havens to weather the mounting risk," he said in a commentary.

France's right-wing candidate Francois Fillon has been embroiled in a money scandal and his troubles could boost far-right leader Marine Le Pen, whose campaign echoes many themes that propelled Donald Trump to the White House.
Le Pen's list of 144 "commitments" to the nation include pulling France out of the eurozone.
"The French election is one of the biggest risks of this year, and if Le Pen wins within this climate of increasing anti-globalism, there's the risk that the European Union will collapse," Toshihiko Matsuno, a senior strategist at SMBC Friend Securities, told Bloomberg News.
