Pine Tree and Phoenix Hall.
The almost 1000 year old Phoenix Hall at Byodoin temple is currently undergoing restoration works and it will be under covers until 2014. The good news is they are only charging 300yen to enter the grounds and you can still see they gardens, the museum, and all of the other buildings.
It is a condition of entry of Byodoin Temple that any photos taken there are not used for commercial purposes. The funny thing is: an image of this temple is on the 10 yen coin, and that's being used for commercial purposes every day.
