We did have a little turbulence as we neared Japan on the PDX-NRT route yesterday. Nothing really bad though.
My feeling is that airlines will usually try to fly, if at all possible, in these situations. A few years ago on a west coast-NRT flight as a typhoon was hitting Japan, they didn't cancel the flight, but they did lighten the load by bumping (involuntarily) a sizeable number of passengers.
