On a beautiful crisp winter day in January 2014, I rode completely around the Imperial Palace Grounds and Gardens, the home of the Japanese Royal Family. I also met some nice people (and cute girls!) on the way and got to see some lovely sights. My company, TokyoBikingTours.com offers bicycle tours of this and many other attractions in Tokyo.This route is very popular for runners and bikers and is one of the most popular tourist attractions in Tokyo. It is particularly popular during the upcoming cherry blossom festival in April. Most of the old trees that you see lining the bike path are very old cherry trees.
