<strong>2005 assets at risk:</strong> $215.6 billion

Osaka has a coastline stretching 230 kilometers (143 miles) along Osaka Bay, where its population and businesses are concentrated.

A 1934 typhoon killed more than 3,000 people, its 18-foot storm surge destroying 43,000 buildings in and around Osaka. More than 200 people died in a 1961 typhoon, which wrecked 15,000 houses.

In the two decades after the 1961 Muroto II typhoon, municipal engineers built embankments, steel barriers, 80 pumping stations and six spillways.

Osaka's storm surge and risk of sea-level rise is exacerbated by land subsidence caused in part by groundwater pumping.
