Masahiro Hara Takes Aim: The QR Code Inventor Builds Post-Pandemic Applications

Conceived in the early 1990s, the QR Code has spread exponentially during the pandemic. Its creator, Masahiro Hara, is one of the many continuing to innovate his most famous invention, which has changed everything from medicine to how we dine.

There's a small red sign at the foot of the steps leading to the Haiden pavilion of Futarasan-jinja, a Shinto shrine founded in 782 by a Buddhist monk. We are in the heart of a cedar forest in the sacred mountains of Nikko. Before going up to pray to the kami, the spirits of the temple, pilgrims and tourists crowd in front of the sign installed just two years ago.

Smartphones in hand, they scan a QR Code, under a few lines explaining — in Japanese, English, Chinese and Korean — that it is good manners to make a "small donation" when visiting a shrine.
