Aso Shrine (Tokyo)
Aso Shrine is a deeply historical location believed to have been founded in 601, and it is said that historic figures such as Taira no Masakado and Ieyasu Tokugawa visited the shrine for worship.
This place has an old, nostalgic charm and is definitely worth a visit. Right now, you can't go inside, but the outside is open for photos. Still, you can get a really clear view of the whole shrine from outside.
