Around the globe, סאיקו (Sayako 
, סאיקו 
, Curoda 
) is a rare mostly female, but uncommonly masculine first name. The given name סאיקו is habitual in Japan, where it is a rare girly name, India, where it is an extremely rare gender-neutral name, and the United States, where it is an extremely rare dominantly female, but seldom male name. Much less frequently, סאיקו is the last name as well as the forename.
