Police are tightening security in Tokyo as South Korean President Yoon Suk-yeol starts a two-day visit to Japan, the first such trip by a South Korean leader in about four years.
Yoon arrived at Tokyo's Haneda Airport on Thursday. Many police were deployed along roads near the airport. Officers on stand-up scooters were also seen patrolling around airport terminals.
The Metropolitan Police Department says traffic restrictions are in place along sections of expressways and other main roads in Tokyo in accordance with the president's moves in the city. The department says detailed information on the restrictions is available on its website.
Since former Japanese Prime Minister Abe Shinzo was gunned down while campaigning last July, police have strengthened VIP protection.
During Yoon's stay, the police are deploying extra officers for security of the Prime Minister's Office, the South Korean Embassy and other key locations in the capital. Checkpoints are also set up on main roads.
