Walking Around Tokyo Deep Area

It's very popular to walk around Tokyo. There are many books on walking around Tokyo. Many TV programs also are broadcast.
I like walking around Tokyo and my home. Every morning I commute from Shirokanedai to Hamamatsucho on foot. I find some walking routes and some objects such as stone monuments and temples. My favorite route is the ridge line of the Takanawadai Terrace because there are some stone monuments and the Sengakuji Temple in reference to the Forty-seven Ronin.
