The resolution by Japan's parliamentary committee condemned the nuclear test, and urged the Japanese government to take leadership in pushing for tougher punishment against Pyongyang, as measures are being discussed at the United Nations Security Council. Japanese Foreign Minister Taro Kono said it was time to increase pressure on North Korea and eliminate loopholes that allow some countries to continue trading with Pyongyang. Mr. Kono pledged to work closely with the US and South Korea to urge Russia and China to play an appropriate role.

Meanwhile, North Korea has been observed moving what appeared to be an intercontinental ballistic missile (ICBM) towards its west coast, South Korea’s Asia Business Daily reported on Tuesday, citing an unidentified intelligence source. The rocket’s movements began on Monday, a day after North Korea’s sixth nuclear test, and was spotted being transported at night to avoid surveillance, the report said. North Korea has launch facilities for its missile program on its west coast.
