A short train trip from the busiest station in Japan takes you to the base of Mount Takao. It’s a great day hike if you are looking for a relatively easy hike that you can start in the afternoon. There is a a beautiful temple, Yakuo-in, which should not be missed if you’re hiking Takao. I recommend hitting it on the way down the mountain as we did, so you can enjoy the views on the more arduous ‘A’ route. You could also cheat and ride the cable car if you’re shy on time, but that’s no fun.
