After a long hiatus...

This company originally started off producing a card game called Hanafuda. This became a big success and they started using Disney characters in their cards very soon. After their success in this area, they soon started a taxi service and also produced toys and stuff. But, this didn’t attract much clientele. So, in the 80s they conceived a game called Donkey Kong which became a craze very soon. They started concentrating on this track from then on. Currently, it poses threats in this area to Microsoft and Sony. Which company?
