The Department of Foreign Affairs (DFA) reported that no Filipinos were hurt when a man in a Joker costume launched an attack on a train in Tokyo, Japan on Sunday, October 31.

The DFA made the assurance following reports that 17 people were injured during a knife and arson attack by a man clad in a green shirt and purple suit near Kokuryo station on Halloween night.

"Based on a report from our embassy, no Filipinos were hurt in the attack," the DFA said Monday afternoon.

Halloween has always been a festive occasion in Japan wherein partygoers wear costumes outdoors and party on the streets of Japan, including the busy Shibuya district, to celebrate.

However, it was reported that a man staged an attack on a Tokyo train, sending passengers into a frenzy. Photos and videos of the incident were posted on various social media platforms.

A report by Nikkei Asia said that the man identified as Hattori Kyota, 24, told police investigators that he "adores" the iconic comic book antagonist Joker.

Hattori, who was arrested at the scene on suspicion of attempted murder, was also quoted as saying that he "wanted to kill people and be given the death penalty" and that he had been thinking of being sentenced to death since June this year.

The police said the suspect chose a limited express train bound for the city center that makes few stops because it is generally crowded with passengers. Hattori reportedly expressed regret at failing to kill anyone in the attack.

According to the Nikkei Asia report, a man in his 70s was in critical condition after allegedly being stabbed by Hattori in the chest as the Keio Line train was moving around 8 p.m. The suspect also allegedly started a fire on the train using lighter fluid.

The other 16 victims sustained minor injuries including smoke inhalation.

Meanwhile, Hattori was quoted as saying he had "failed in work and had troubles in relationships with his friends."
