Koreans have the third-most powerful passport in the world, according to an annual index by the Swiss-based research firm Henley and Partners released on Sunday.

The firm ranks passports based on the number of countries people can visit visa-free. Koreans can travel to 191 countries without obtaining a visa beforehand, the same number as Germany.

Korea's ranking remains the same as last year.

Japan's passport continues to top the list, granting access to 193 countries, followed by Singapore with 192.

The research firm noted that the rankings do not take into account travel curbs for the coronavirus pandemic.
