Todoroki Keikoku, the only valley in Tokyo’s 23 wards, is located within a three-minute walk/three minutes’ walk from Todoroki station on Tokyu Oimachi. You see a small river and a trail there. It is cooler and quieter than outside. It is very comfortable place but you should wear hiking boots because the trail is covered with mud. If you wear high heels, you could slip and fall into the river. The final destination is Todoroki Fudoson, which is a Shinto shrine. You can drink green tea and eat kuzu mochi, anmitsu. It takes 30 minutes from the station.
