Carol ChenThe Henley Passport index ranks Singapore passport as # 1 with the most visa-free destinations. Japan & S.Korea are 2nd and Finland 3rd (with several EU countries): https://www.henleyglobal.com/passport-index/ranking
The VisaGuide Passport Index however puts different weights on visa-free (1), passport-free (1.01), eTA (1) and visa on arrival (0.8). This gives all the passport-free #Schengen countries a slight advantage, bumping Finland to # 1 and Singapore to # 2. Japan drops to 13th having more VOA destinations, and S.Korea in 29th place with 9 entry-ban destinations. More nuanced (and maybe more accurate) score?
