Japanese and Singaporean passport holders have the greatest travel freedom worldwide, with visa-free access to a record 180 countries, according to a survey by the law firm Henley & Partners.

According to the 2018 Henley Passport Index Ranking released Wednesday, Germany fell to second, with visa-free access to 179 countries, after ranking first for the past five years.

"Japan and Singapore rose to the top of the index after, among other developments, Uzbekistan lifted visa requirements for Japanese and Singaporean nationals in early February," the firm said on its website. "Uzbekistan's efforts to increase tourist inflows saw a number of other countries in Asia and the Middle East (including Turkey, Indonesia, and Israel) gaining access."
