The Institute for Nature Study is a ten minute walk from Meguro Station. From the station, take the East Exit. There will be a huge main road, Meguro Dori, to your right. Cross the road toward McDonalds and continue straight along Meguro Dori for about six minutes. Eventually, on your left hand side you will see many trees. This marks the entrance to the Institute for Nature Study.
