Which is better for…

Your budget

It's a wash

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

Your career

Depends on your field

Both run on local + English at work, so the edge comes down to your sector. Osaka: Pharmaceuticals & life sciences, Electronics & manufacturing, Trading & commerce. Ulsan: Automotive, Shipbuilding & offshore, Refining & petrochemicals.

Your lifestyle

Depends what you want

Osaka feels like “Japan's merchant city — cheaper than Tokyo, blunter about everything, and it stands on the other side of the escalator”, while Ulsanis “Hyundai's company city — the world's biggest car plant, a shipyard, and Korea's highest output per head”. Climate is a real differentiator: Osaka — humid subtropical — hot and very humid summers, mild winters, a june rainy season and typhoons in september. Ulsan — humid subtropical and coastal — milder winters than inland korea, humid summers, a july rain season, and typhoons that make landfall on this stretch of coast.
