Pokemon Co., partly owned by Nintendo Co., unveiled several new initiatives at an event in Tokyo, including a game inspired by the "Detective Pikachu" film for the Switch console and a new device for tracking sleep.

The Detective Pikachu title aims to cash in on the popularity of the eponymous movie released this month. The game could further boost demand for the Switch, although Pokemon did not announce a release date.

Another new game, Pokemon Sleep, aims to turn sleep into "entertainment" by recording when the players go to bed and wake up and what times of the day they sleep, although more details will be unveiled at a later date.
