If you are in the Yanaka or Sendagi area please visit Nezu Shrine! (located in Bunkyo Tokyo, Japan)
It is a great place to escape the busy scene in Tokyo. I recommend visiting early in the morning as the shrine can be very quiet and peaceful.
Known for its several Tori gates resembling traditional Tokyo and Kyoto.
Address: 1-28-9 Nezu, Bunkyo-ku, Tokyo
Access: 1km walk from Sakura hotel Nippori and Five minute walk from Chiyoda Nezu Station
