Police in Tokyo are increasing security around stations near the course of the Tokyo Marathon to be held on Sunday. It is one of Japan's biggest races of its kind.
The 16th Tokyo Marathon will be held with about 38,000 runners participating. The figure has returned to the pre-pandemic level.
About 30 police officers and station personnel conducted a joint patrol of two stations near the course in Minato Ward on Wednesday.
Police officers used sniffer dogs to check for suspicious items in stations and elsewhere.
Security at the Tokyo Marathon will be carried out on a large scale ahead of the Group of Seven summit in Hiroshima in May.
The Tokyo Metropolitan Police plan to take thorough measures to ensure the safety of runners and spectators, including deploying many police officers.
Takayama Yusuke, who is in charge of security, said he wants people to inform police if they see any suspicious persons or suspicious items, calling on citizens' vigilance to prevent terrorism.
