Surging coronavirus cases in Shanghai are hurting businesses in Japan. The city has been in lockdown since late March, resulting in supply chain bottlenecks and a shortage of truck drivers.

Some companies involved in Japan's auto industry have been forced to halt production.

Japanese-affiliated company Shanghai Marukyo Logistics says there is a shortage of people who can transport freight to Shanghai's port, which handles the world's largest volume of containers.

Restrictions on vehicles are also preventing the company from receiving parts from areas including Jiangsu Province.

Company executive Tanaka Akihiro says the restrictions appear to be getting stricter each day.

Authorities in Shanghai are yet to announce when the restrictions will end.
