A surprised passenger on a Tokyo subway train had a strange encounter with a train-riding turtle last week. According to UPI, Yuki Nakajima was on the Toei Shinjuku line when he spotted the loose turtle crawling around with no signs of a human companion. "He was so relaxed and freely walking until gradually everyone began to notice him and he became a star,” Nakajima explains. "We all laughed along with each other and watched the turtle walk around, taking pictures of him.” Railway staff ultimately took the turtle off the train at a later station and police are now trying to find its owner.
