In response to a series of knife attacks on Japanese trains, JR West is introducing extra-long umbrellas with canopies to help passengers defend themselves. The new umbrellas will be deployed on 600 trains in the Kansai region and are designed to provide an effective shield against potential assailants. With their increased length and sturdy design, these umbrellas aim to offer a safer alternative for those caught in violent incidents.
