In Japan, what buildings are illegal to take pictures of?
- Building only. Zero humans on the picture.
- Taken from public street only. No entering private property/shops/transportation or similar.
Context: Loving architecture I always take tons of pictures when walking in the street, and sometimes get scolded by security guards. When talking with them they sometimes claim that some laws ban taking pictures of the building they protect, but without being able to tell me what law in particular.
