Thank you , Hamao-sensei. We enjoyed your class very much.
This class was held at "Institute for Nature Study", one of the branch institute of the National Science Museum, located in Meguro-ward. Believe or not, it's a real forest surrounded by Tokyo concrete jungle.
Actually, I've intrroduced some gardens(Rikugien, Furukawa-teien, etc) as the nature spot in Tokyo on this weblog, but they were sort of "artificial nature". I didn't know there was a such kind of real nature reserve in the center of Tokyo. I heard that this place has been designated as a national natural monument since 1949.
"If you're lucky, you can come across Kawasemi." A bird watcher who talked with us said so. Coming across Kawasemi in Meguro-ward? Really?
