Barely six months after inaugurating a tiny software-coding boot camp in a basement in Tokyo, Silicon Valley transplant Kani Munidasa stood before some of Japan's top business leaders in February with a warning: Software was threatening their future.

A Sri Lankan native with a Japanese mother and wife, Munidasa was speaking at the invitation of Nobuyuki Idei, a former chief executive of Sony Corp.

Idei had offered to become an adviser to the boot camp, called Code Chrysalis, whose mission of bringing Japan's software engineering up to global standards and helping its companies transform aligned with his own.
