What is the English word for Oba Chan?

"Oba Chan" is a Japanese term, not an English one. It translates to "Auntie" in English, specifically referring to an older woman, usually someone's aunt or a neighborly figure.

However, it's important to note that "Oba Chan" is not just a simple translation of "Auntie." It carries a specific cultural nuance in Japanese society, often conveying respect and affection for older women.
