Gojôten Jinja
Another shrine tucked away in Ueno Park, this shrine is not as flashy as Ueno Tôshôgû, but it is far more accessible and has its own little bits of beauty. There isn't any information that I know particularly about this shrine other than it too used to be a part of the Kaneiji temple complex which covered what is Ueno Park today, and it is home to a small Inari shrine as well as a city shrine to the people and prosperity of Ueno.
