TOKYO: Japan's heavy bond issuance to fund economic support measures during the pandemic has made the need for fiscal reform even more pressing, Finance Minister Taro Aso said on Friday.

Speaking to reporters after a cabinet meeting, Aso said Japan has so far avoided a spike in government bond yields and a sudden yen selling, thanks in part to the Bank of Japan's monetary easing.

"Given a jump in new bond issuance, however, the need for fiscal reform has become even more severe," Aso said. "We must cope with the coronavirus and achieve our primary aim of economic revival and fiscal reform," Aso said.

Japan's cabinet decided on Friday to spend 741.8 billion yen ($7.15 billion) in emergency reserves to pay up to 1.8 million yen a month to bars and restaurants complying with shorter hours to prevent the coronavirus from spreading further, the finance ministry said.

The amount, which comes on top of cumulative spending of 5.09 trillion yen, will leave the government with 5.66 trillion yen in coronavirus emergency reserves earmarked in the state budget, it said.

Prime Minister Yoshihide Suga's government put priority on the coronavirus response and economic revival over fiscal reform as it has rolled out a combined $3 trillion in economic packages -- two-thirds the size of Japan's gross domestic product.

Japan is saddled with public debt burden at more than twice the size of its $5 trillion economy, by far the largest among industrial nations due to years of heavy stimulus and the snowballing social welfare costs of a rapidly ageing population.

On Thursday, a prominent cabinet minister, Taro Kono, said Japan could consider fresh economic stimulus, including a possible fourth extra budget, as the government expands a state of emergency amid a record surge in coronavirus infections.
