This marked Tokyo's second revision higher after previously giving estimates of 70 and 120 kilotons.

Defence Minister told reporters that his ministry's upward revision to 160 kilotons was based on a revised magnitude by the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO).

"This is far more powerful than their nuclear tests in the past," Onodera told reporters.

Early Wednesday, Onodera held telephone talks with US Defense Secretary Jim Mattis and both agreed to step up "visible pressure" on North Korea, the ministry in Tokyo said.

"North Korea's nuclear and missile development is at a new stage of grave and imminent threats," Onodera told Mattis, the ministry said, adding that his US counterpart shared the view.

Pyongyang's Sunday test of what it described as a hydrogen bomb designed for a long-range missile triggered global alarm and has divided the community as it scrambles for a response.

Japanese Prime Minister Shinzo Abe is expected to press Putin for his support over the North Korea's provocation, when the two leaders hold talks in the Russian Far East city of Vladivostok on Thursday.

"We have to make change its current policy and understand that there is no bright future if continues the present policy," Abe told reporters ahead of his departure.
