Whatever the belief system or whoever they're dedicated to, shrines have a way of making you contemplative. Check out Gojoten Shrine and share a peaceful moment with the locals.
You'll find Gojoten Shrine in the commercial ward of Taito. It's free to enter, so you can leave your credit card zipped up in your bag. While you're in these parts, why not cross off some other great sights, such as Tokyo Sky Tree, Tokyo Tower and Tokyo Imperial Palace?
