Yoshioka is a Japanese surname composed of two kanji: yoshi (吉), meaning "good luck" or "fortune", and oka (岡), meaning "hill" or "ridge". This topographic surname likely originated from a place name describing a lucky hill or a ridge that brought prosperity. The surname is common in western Japan, particularly in the Kansai and Chubu regions.
Geographic Connection
The surname is shared with the town of Yoshioka, Gunma, a town located in Gunma Prefecture, Japan. As of September 2020, Yoshioka had an estimated population of 21,749.

The western half of the town is elevated between 200 and 900 meters, while the eastern half is flatter, ranging from 100 to 200 meters.
