Yen fell off two-week highs against the dollar after North Korea opened the door for negotiating solutions with the US even after President Donald Trump canceled a June summit with Kim Jong Un.
USD/JPY fell to 109.56 from the opening of 109.24, with an intraday low at 109.10, and a high at 109.74.
After safe havens yen and Swiss frank marked good gains on Thursday on global political tensions, traders sold their holdings on Friday to collect profits before a long US weekend.
Trump has blamed "open hostility" from the North Korean side as cause for scraping the talks, while warning that the US army is ready in case North Korea committed any aggressive act.
Yen is still heading for a weekly profit nonetheless after eight long weeks of losses.
