Originally posted by RobG I'd certainly like to! The lanterns remind me of a similar arrangement I saw at a shrine in Shinjuku.
The one in Shinjuku is good too. I think Shinjuku is doing it during winter months. It for new year cerebration.
The one in Yasukuni is for Obon cerebration. Below image might give a better idea.
First photo is about 1/3 of the lantern displayed. it is half way to the shrine.
Another 1/3 is in the last image which I took just before enter the shrine.
And the last 1/3 is inside the shrine.
It is about 30,000 lanterns in total. The festival will be on July 13 - 16 every year. Highly recement to go if you can ignore the infamous part of the shrine.
