Near my company's GHQ in Osaka there is a temple that I love to take photos of. These are the lanterns that run across the front of one of the buildings. There's also a small historical record building / museum, shrines and other small structures throughout the area. It's not particularly large, being rather close together, but it's beautiful and never particularly crowded. I tend to go before heading to work if I do an overnight business trip to Osaka.
