Mitakesan (御岳山) to Odakesan (大岳山) to Okutama is a nice dayhike from Tokyo easily reachable by public transportation. It's a bit more challenging than other hikes in the area, has scenic views from Odake and ends in Okutama with a beautiful blue river and an Onsen.
Elevation Gain: 860m
Take the orange JR Chuo Line to Ome station and then transfer to the JR Ome Line to Mitake station. Cost is 945Y.
Depending on which train you take you might also have to transfer at Tachikawa.
The ropeway costs 600Y one-way. First one is at 7:30.
If you come by car you can park at the ropeway or a bit lower.
Start from the top of the ropeway and make a quick detour to the Mitake Shrine. After that follow the signs for "Mitake Rock Garden". You'll pass a little waterfall and follow a small stream up. Since there are a lot of signs and trails it can be a bit confusing and I recommend downloading Yamap and the offline map for the mountain (Mitake,yama, Tokyo).
Follow the signs for Odake and just before getting to the peak you'll get to an old hut and toilets. The trail has a couple of steeper sections and some chains but its generally easy. From the peak you can either turn back or continue down to Okutama. This will add about 3h walking time. I really enjoyed this section as there was barely any people and there are a couple of little ladders and lots of roots to climb up and down with.
At the end of the trail you'll get out at old pagoda and a reeeally long staircase. Now you have the option to make a small detour to an Onsen or head straight back to Tokyo. I always love a bath after hiking so I stopped by. Bring a towel and a change of clothes.
There are some guesthouses close to the ropeway, I would check Rakuten (Japanese one with google chrome) or the places directly from their websites.
