A man armed with a knife has killed seven people and injured 10 others in central Tokyo, Japanese media say.
The incident occurred in the Akihabara district, a busy shopping area known as Electric Town that is popular with young people and tourists.
A suspect, said to be 25-year-old Tomohiro Kato, has been arrested.
Police spokesman Jiro Akaogi told reporters: "The suspect said he came to Akihabara to kill people. He said he was tired of life".
The dead include six men, ranging in age from 19 to 74, and a 21-year-old woman, Kyodo News said.
Reports say the suspect drove a rented truck into a crowd in the early afternoon and then began stabbing people at random.
Is it me, or does it seem weird over there? People are killing themselves with household chemicals and now this story?
Just wondering. And, yes, it's fair to bring up the fact that American's weirdness emanates entirely from Florida.
