In an online survey conducted by the National Police Agency in October last year, 67.1% of respondents felt public safety in Japan had declined over the past 10 years, possibly affected by former Prime Minister Shinzo Abe's assassination in July as well as a number of stabbings in recent years. The 5,000 respondents, age 15 and older, cited random killings, defrauding by impersonation and child abuse as among crimes that came to mind. The negative perception comes after three people were knifed outside the University of Tokyo ahead of nationwide entrance exams in January last year, while a woman and her daughter were stabbed by a girl in the capital's Shibuya district in August. The country was additionally rattled by Abe's assassination on July 8, when the former prime minister was shot at close range during a campaign speech ahead of a national election. There have also been a number of attacks on trains and in train stations in recent years, including a knife attack on a Tokyo train on the night of Halloween in 2021 in which 17 people were injured.
