I hope you are all enjoying the holiday season. The picture you see is of the lights in front of the Saishukan Building in Obiyama, near my home, and was taken from the following site:

In addition to lights in front of their Obiyama offices, Saishunkan used to put on an extremely impressive display on the way to the airport, but, as far as I know, that has been discontinued. For other illumination options, check out this “best illumination in Kumamoto” site (in Japanese):
