If you’re comfortable with hiking 6-8 miles in a day with moderate elevation gain (1800-1900 feet), this is a pleasant hike that’s easily accessible from base. We initially found out about this hike from the following link, which has more details as well as information on other hikes in the area: https://ridgelineimages.com/hiking/mt-iwatakeishiyama/
As the hike starts and ends at Ome Line train stations (Mitake and Ikusabata), the logistics are fairly easy — no buses involved. To access the start of this hike, take the train from Fussa Station (Ome Line) to Mitake Station (towards Okutama). It may be necessary to transfer in Ome; as not all trains are direct — check Google Maps to confirm.
Once you get off the train in Mitake, stop by the Visitor Information Center (can’t miss it – its directly by the stairs leading down from the station exit) and pick up an “Ohtama” area map. If you ask, they’ll also be able to provide a map of this specific hike, and a paper showing directions to the trailhead. I’ve attached these directions to this post as well, for reference.
The trailhead starts near a temple a few minutes away from the train station. Go down the stairs at the station exit, and turn left at the street. You’ll pass an ATM on your left (inside its own building), and will see a set of stairs on the left immediately after the ATM. Go up the stairs and cross the train tracks. Turn left, and then turn right into the temple entrance (you’ll see the temple). Once just inside the temple, go to the left, and you’ll see the trailhead marker.
As you go along the hike, you’ll see signposts with kanji, but also English in small labels below. At the start, you’ll want to follow the signs for “Mt. Iwatakeishiyama 岩茸石山”. Once you’ve reached Mt. Iwatakeishiyama, then follow the signs for “Ikusabata Station”, which is the finish point where you’ll catch a train back towards Fussa Station.
The hike starts with a fairly quick ascent; but (mostly) levels off after that point. There are two points where you have the option to either ascend to a peak for a better view, or keep going. Recommend taking the climb up to Mt. Iwatakeishiyama for a view — you’ll likely also see a large number of Japanese hikers taking a snack break here. If you choose to ascend the fork to the peak, there is no backtracking required to get back to the main trail — the fork continues down the other side of the peak and rejoins the main trail.
Continuing on, you’ll come to a temple in the mountains, right along the trail. Its a nice spot to take a break and look around, and there are bathrooms here (did not check them out, but expecting squatting/pit style). Descending from here, you’ll enter a fairly exposed valley, and continue down past a stream. As you continue downward, you’ll come to a large manmade dam, and the trail becomes a stone stairway. Look out for snakes sunning themselves along the steps; they should be easy enough to spot.
As we reached the end of the stairway, we came to a Japanese shop that offers some drinks at picnic tables outdoors (beer, coffee, lemon sour, water) as well as cooked fish. My Japanese wasn’t great, but we were able to understand well enough the owner’s indicating that ‘everything is OK to eat’ on the fish, as its cleaned and cooked whole and ready to eat (skin and all), which might be unfamiliar to some folks. The owner was very friendly, and everything was pretty reasonable – we got two cooked fish and one coffee for under 1000 yen. Be sure to bring cash if you’re planning to stop here, as I don’t imagine this shop takes credit card.
After this shop, the ‘trail’ becomes a road, keep going onward and it will merge into a slightly larger road. Bear right, and continue. Eventually, you’ll come to a point where there is a sign pointing towards Ikusabata Station up a small road on the right – take this road upwards, and you’ll cross train tracks. Turn right, and you’re at the station. Take the train back towards Fussa. This is all shown on the maps as well; and if you download offline maps on your phone before the hike, you can also ‘mark’ the location of the station if you’d like to be able to double-check along the way. – Joshua Milburn, April 2019
