Japan once again tops the list, as Japanese passport allows its holder to travel freely to as many as 190 destinations throughout the world. By contrast, the weakest passports - those of Afghanistan and Iraq - grant visa-free access or access with a visa-on-arrival to no more than 30 countries.

According to the latest Henley Passport Index, which draws on data from the International Air Transport Association (IATA) and covers 199 passports and 227 travel destinations, the passport of Bosnia and Herzegovina is ranked joint 40th in the world, as it allows the citizens of BiH to travel freely to 118 destinations.

The average passport lets its holder visit 107 countries without needing a visa - compared to only 58 back in 2006 - meaning that visas are being liberalized and travel freedom is increasing.  

An average European citizen can travel freely to 163 destinations. Slovenian passport grants visa-free access to 180 countries, Croatian to 168, Serbian to 129, Macedonian to 125, and Montenegrin to 123.
