There are a myriad of stunning illumination events across Japan during the colder months, and a new one on the calendar adds a National Treasure into the mix. The Matsumoto Castle Illumination event preserves the castle structure by utilizing projection mapping technology in lieu of standard LED lights, and their reflection on the castle's moat creates an ultra-photogenic scene.
The event runs right from the beginning of December until the end of February, so if you're in the area this winter be sure to stop by.
