As I heard the story, a few years ago an artist put together a nighttime display of thick bamboo drilled with holes of varying sizes on one side and big holes on the other. The big holes are to release the heat and to accept the candles placed in strategic spots. The display was popular and is now shown in Downtown Kumamoto at night as the festival described below continues. It's impossible to take a shot without others in it, so sorry about that. Please enjoy.
