In all the world, Isan (Isan , Исан , อีสาน ) is quite a common principally masculine, but very infrequently girly given name. The given name Isan is characteristic of Kyrgyzstan, where it is quite a rare masculine name, Indonesia, where it is quite a rare predominantly male, but very infrequently female name, and Sri Lanka, where it is a rare boy's name. Measured by absolute frequency, it most frequently occurs in India, Indonesia, and Japan. Much less frequently, Isan is the last name as well as the forename.
