I use the Japanese equivalents to decide where to visit in Japan in fall. Quite handy.

My first visit to Japan was late last fall. Tokyo around the 25th, Hiroshima before the end of the month, Miyajima Island, and working my way back north through the 13th of December.

I had heard the colors around Kyoto would peak in November, but I certainly didn't expect it to be so beautiful into December.
