Appearing together at news conference on Thursday in Tokyo, Toyota Motor Corp. President Akio Toyoda and SoftBank Group Corp. Chairman Masayoshi Son recounted an episode 20 years prior that put the two at loggerheads over a proposed business venture.

Fast forward 20 years and the two were gleefully laughing off the incident as they celebrated the launch of a joint business, Monet Technologies Corp., which will offer on-demand services ranging from food delivery to medical care.

During their discussion, Toyoda did not shy away from the fact that times had certainly changed.
