TOKYO (REUTERS) - The total number of Japanese novel coronavirus infections hit more than 5,300 on Thursday (April 9), NHK public broadcaster said, showing no signs of slowing despite a state of emergency being imposed this week on Tokyo and six other areas.

Tokyo’s nightlife districts of Shibuya, Akasaka and Ginza areas were much quieter than usual overnight as the state of emergency took effect, but cities have not shut down and many workers are still commuting to offices by day.

The central bank warned that the coronavirus pandemic had created an "extremely high" level of uncertainty for the world’s third-largest economy, with regional economies facing their worst conditions since the global financial crisis a decade ago.

Japanese authorities are hoping to contain the outbreak without imposing a mandatory lockdown that could deal a major blow to an economy already struggling to cope with the virus outbreak.

Once declared by the central government, the state of emergency gives local governors stronger legal authority to urge people to stay home and businesses to close.

In contrast to stringent lockdowns in some countries, mandating fines and arrests for non-compliance, enforcement will rely more on peer pressure and a deep-rooted Japanese tradition of respect for authority.

Japan, where a cruise ship offshore was once the biggest source of infections outside China, had early success in limiting the coronavirus.

But authorities have become more alarmed in recent weeks by a surge in local transmission.

The number of infections rose by 384 on Thursday to 5,356, while the death toll edged up by 1 to 106, according to NHK.

During a daily live YouTube broadcast, Tokyo Governor Yuriko Koike said the capital had 181 new cases on Thursday, the highest daily jump.

"I am asking for your cooperation to protect your life, protect your family, protect your colleagues and society," she said.

While Tokyo and the central government have been discussing what kind of businesses they will ask to close, Ms Koike is considering making her own decision if they fail to reach an agreement, Kyodo news agency reported.

Mr Hideaki Omura, the governor of the central Japan prefecture of Aichi, said he would declare a state of emergency on Friday even if the central government did not add it to the national list of emergency prefectures.

Mr Aichi includes the city of Nagoya and hosts Toyota Motor Corp.

"If we watch what’s happened in the last week it doesn’t look good and so we’re making preparations," he said.

Chief Cabinet Secretary Yoshihide Suga said in an afternoon press briefing that there was no need now to add Aichi and other areas to the national list.

ECONOMY ON BRINK

Even with less stringent restrictions compared with other countries, analysts polled by Reuters expect Japan to slip into a deep recession this year as the virus outbreak wreaks havoc on business and daily life.

While aggressive central bank actions across the globe have eased financial market tensions somewhat, corporate funding strains were worsening, Bank of Japan Governor Haruhiko Kuroda told a quarterly meeting of the bank’s regional branch managers on Thursday.

"The spread of the coronavirus is having a severe impact on Japan’s economy through declines in exports, output, demand from overseas tourists and private consumption," he said. "For the time being, we won’t hesitate to take additional monetary easing steps if needed, with a close eye on developments regarding the coronavirus outbreak."

The BOJ cut its assessment on all of Japan’s nine regions for the first time in 11 years, saying their economies were weakening or under strong downward pressure.

"The situation is quite severe. Business sentiment is souring. Firms dealing with inbound tourism and consumption are seeing sharp declines in sales," Mr Yasuhiro Yamada, the BOJ’s Osaka branch manager overseeing the Kinki western Japan region, told a news conference.

Shares of Oriental Land Co fell on Thursday after the operator of Tokyo Disneyland said it would keep the amusement park shut until mid-May.

Entertainment facility operator Uchiyama Holdings said it was closing 43 karaoke shops and 11 restaurants until May 6.

Fast Retailing said sales at its Uniqlo outlets were down 27 per cent in March from a year earlier.

But retail group Seven & i Holdings Co reported a 3 per cent rise in annual operating profit, thanks to robust sales of food and other daily necessities.

Mr Kuroda’s remarks highlight the strong concern policymakers have over the outlook for Japan’s economy and how companies continue to struggle to generate cash, despite government and central bank promises to flood the economy with funds.

At its policy meeting later this month, the BOJ is likely to make a rare projection that the economy will shrink this year, sources have told Reuters.

The BOJ eased monetary policy in March by pledging to boost purchases of assets ranging from government bonds, commercial paper, corporate bonds and trust funds investing in stocks.

The government also rolled out a nearly US$1 trillion (S$1.42 trillion) stimulus package to soften the economic blow.
