Great for Exploring
I lived in Tokyo for a year, so my review is going to be very biased. While Tokyo doesn't have a lot of temples, it does have parks (Yoyogi, Inokashira, Yurakucho) and lots of amazing districts to go to.
Insider Tip:Go to Harajuku, Omotesando-dori exit, and go straight and take the first right. Then you can continue to Yoyogi Park and straight into Shibuya. It's a great afternoon walk especially on weekends, where you can see wandering musicians.
