An elderly Japanese man and his giant African pet tortoise BonChan have become an Internet sensation after pictures of them walking around parts of downtown Tokyo went viral. When the tortoise is not enjoying a walk, he lives in a wooden enclosure designed by the owner himself and chomps on vegetables and fruits, including carrots, lettuce and apples. Bon-chan, also named Master Roshi in reference to a character from the popular Japanese cartoon series Dragon Ball Z, has not been weighed in a while but the owner thinks that his pet is probably around 70 kilograms. The Japanese holiday O-bon inspired the name Bon- chan which were taking place around the time when the tortoise was bought by the owner's wife. details please​
