Mt. Mitake is one of Tokyo's easily accessible peaks via cable car. But it still requires a good deal of climbing up slopes and steps. You can also hike to adjacent Mt. Hinode-yama. Great daytrip getaway from Tokyo's concrete jungle.
Getting off the train at Mitake Station on the JR Ome Line. I wasn't the only one who decided it was a good day to hike up Mitake. 御岳駅
