The new chief of Japan's National Police Agency says officers across the country must do their utmost to ensure the security of the state funeral of former Prime Minister Abe Shinzo.

The agency held an extraordinary meeting in Tokyo on Wednesday. About 90 people attended, including the head of each prefectural police department and senior officials from the agency.

It comes after Abe was fatally shot while giving an election campaign speech in July. The attack has led to a review of how to guard VIPs. Tsuyuki Yasuhiro assumed the post of the agency's commissioner general last week.

Tsuyuki told the participants that his agency must take seriously the fact that the police failed to fulfill their responsibility to protect VIPs, and that they need to drastically strengthen security protocols in order to regain trust.

He instructed the officials to be ready to create security plans for areas where VIP protection is frequently deployed. He said the plans must be based on newly revised rules.

Tsuyuki referred to Abe's state funeral, planned for Tokyo in late September. He said it will be the first large-scale security operation to be held under the new rules. He also said officials across the country need to work together on their tasks, including mobilizing officers and gathering relevant information, for the prestige of the police.
