A typhoon that tore through Japan leaving 11 people dead and hundreds injured has damaged the country’s third-largest airport so badly that it may be closed for at least a week, officials said on Wednesday.

With the storm now heading offshore as a low-pressure system, a major concern is the longer-term effects on business and tourism.

Referring to the damaged airport, Akira Yoshimura, a manager in the economic research division at MUFG Bank, said, “If Kansai Airport doesn’t open for a long time, it may impact not only the economy in the Osaka area but on the whole nation, to some extent,” according to remarks reported by the Japanese broadcaster NHK.
