Your budget

It's a wash

Busan and Osaka cost about the same month to month once rent and everyday spending are combined.

Your career

Depends on your field

Your lifestyle

Depends what you want

Busan feels like “Korea's port and second city — beaches, a blunt dialect, and rents well below Seoul's”, while Osakais “Japan's merchant city — cheaper than Tokyo, blunter about everything, and it stands on the other side of the escalator”. Climate is a real differentiator: Busan — milder than seoul and rarely snowy, with humid summers, a july rain season and typhoons that arrive as storm surge rather than rain. Osaka — humid subtropical — hot and very humid summers, mild winters, a june rainy season and typhoons in september.
