WITH THE LARGEST CONCENTRATION of broad-leafed evergreens in Japan, mountainous Chichibu-Tama-Kai is an ideal place to put into practice the newest principles of wellness science. In a grove of rod-straight Japanese red pine, Kunio pulled a thermos from his massive daypack and served us some mountain-grown, bark-flavored wasabi-root tea. The idea with shinrin-yoku, a term coined by the government in 1982 but inspired by ancient Shinto and Buddhist practices, is to let nature enter your body through all five senses, and this was the taste part. I stretched out across the top of a cool, mossy boulder. A duck quacked. I was feeling pretty mellow, and tests would soon validate this: between the beginning and the end of the two-hour hike, my blood pressure had dropped a couple of points. Ito’s had dropped even more.
We knew this because we were on one of Japan’s 48 official Forest Therapy trails, designated for shinrin-yoku by Japan’s Forestry Agency.
