There are 37 million people living in Tokyo, and we've all perfected the art of absolute indifference as we pass each other on the streets, stand next to each other in lines, and share space on the trains. An electricity grid flowing at light speed. But sometimes, if you are careful and keep your eyes open, sometimes you can catch a moment, a connection - a spark as it happens. Momentarily threatening to derail it all, and then, just as quick, it's gone.

Don't blink or you'll miss it.
