Like other major Western noble titles, Viscount is sometimes used to render certain titles in non-western languages with their own traditions, even though they are as a rule historically unrelated and thus hard to compare which are considered 'equivalent' in relative rank.
This is the case with:
- the Chinese Tzu or Zi (子), hereditary title of nobility first established in the Zhou dynasty
- the Korean cognate jajak or Pansoh
- the Japanese cognate Shishaku (子爵) or Shi, fourth of the five peerage ranks established in the Meiji era, based both on the British viscount and Zhou Chinese zi
- the Vietnamese cognate Tử
- the Manchu jingkini hafan
