Japan's Prime Minister Kishida Fumio says he will coordinate plans to tap into the government's reserve fund for the third time to speed up the reconstruction of areas devastated by the New Year's Day earthquake.

Kishida attended a government taskforce meeting on the Noto Peninsula earthquake in central Japan. The governor of hard-hit Ishikawa Prefecture joined online.

Kishida instructed relevant ministers to study the additional use of reserve funds from the state budget for the current fiscal year.

The prime minister said a government office for reconstruction was set up in the quake-hit region on Friday to accelerate work to repair roads and other infrastructure, as well as to build temporary housing.

He said the office will assist in the dispatch of technical staff from across Japan and secure accommodation for workers.

The prime minister also called for a response to damage caused by liquefaction, as well as measures to upgrade wooden temporary housing units after a set period, so residents can live there permanently.

He asked for a new program to be drawn up by the end of this month so that people whose homes were damaged can receive the support they need.

Kishida said government efforts to respond to the disaster should not be held back by budgetary constraints. He urged the ministers to do their utmost to help the disaster evacuees return home and revive the affected areas.
