Japan will need economic measures in the second half of fiscal 2016 after Prime Minister Shinzo Abe said the government will front-load budget spending, according to the vice president of the ruling Liberal Democratic Party.

Implementing this year's budget quickly will help address Japan's weak consumer spending, said Masahiko Komura.

"Then naturally there will have to be something to supplement" after that, he said on NHK's political debate program, without elaborating.

Natsuo Yamaguchi, head of Komeito, the LDP's coalition partner, said on the same program that he suggested that Abe consider fresh economic measures after the Diet passed the budget.

Asked about the possibility of a snap Lower House election, Komura said that it was up to the prime minister.

"I would not say there is zero chance but I don't think there is a big chance, either," he said.
