Yasha is of Hebrew origin, meaning 'God is salvation'. It's a unisex name, often used for both boys and girls, but it's more commonly found as a male name. The name Yasha is pronounced /'jaːʃa/. In some languages, such as Russian, it might be transliterated differently, appearing as Яша or Яся.
"The name Yasha experienced a significant spike in popularity between 1977 and 1980, with over fifty babies named Yasha born each year during this period. However, since the late 1980s, the name's usage has fluctuated but generally declined, with fewer than ten babies named Yasha born annually on average."
