Nintendo Co. has struck a long-term deal to develop augmented reality smartphone apps with Niantic Inc., the Google spinoff whose smash hit Pokemon Go introduced AR to a mainstream gaming audience.

The pair announced a long-term agreement in Tokyo on Tuesday to turn Nintendo content into AR apps, which work by superimposing digital images onto the physical world. They will start by releasing a Pikmin app in 2021, based on the puzzle-solving series created by Nintendo’s creative fellow Shigeru Miyamoto in 2001.

San Francisco-based Niantic becomes Nintendo’s fourth smartphone app development partner, potentially giving the Kyoto-based company’s mobile efforts a much-needed push. Since 2016, Nintendo has developed fewer than 10 smartphone games with outside partners DeNA Co., Cygames Inc. and Line Corp. Nintendo’s shares rose more than 2% in early trading in Tokyo.
