Ascent Trip Report

After our Komaga-take ascent, we travel from Komagana by train back to Okaya then onward via Shiojiri to the small tourist town of Akiso-fukushima. We learn from the information desk across the street from the rail station, that there are no hotels in town and none affordable in the vicinity. Instead we stay at Akisokodo Camping Field, N35.83507 E137.74347, a 4.5km, ten minute drive SE of town (the proprietors come out and collect us), and arrange a taxi for the morning to get us to the first (08:30) cable car on the east side of Ontake (the bus gets there over an hour later and we want to be sure of getting the last bus back from the trailhead). We learn we are only the third group of foreigners to stay here in the last five years! It's a nice spot, with showers, even wifi, also more expensive accommodation is available there.

Tue 25. Our taxi collects us just before 07:00. Four of us plus all the gear cram in; the drive to the cable car station (N35.90178 E137.53736, 1577m; if driving it's well signposted for Ontake Ropeway) takes about an hour giving us time to stow non-hill gear in lockers; the staff look after any items too big for the lockers (for the same fee). Alan and Andrew get a lift down to town later and get the first (08:40) bus. The cable car starts running a few minutes before 08:30 (running continuously: small cars holding 4 people each).

Duane, Adam, Adrian and I start hiking from the top station (N35.90005 E137.51138, 2128m) at 08:50. I push on ahead with Adam as I know I'll be slow going down as I have an injured leg; we have to be back down to catch the 16:20 bus back to town. From the cable car a more or less level path traverses left for ten minutes to reach the Station 7 complex (hut). Shortly afterwards we start climbing rough somewhat slippery steps, keeping R at a fork (N35.89699 E137.50869). Station 8 (hut, refreshments) is at N35.89512 E137.49873; we rest for a few minutes. There should be a R turn at or soon after the hut but we don't see it; anyway the summit route is straight on. We pass a large bell, many Buddha statues, several gateways, even a graveyard. We fork L at N35.89486 E137.48834 just below two huts (Station 9, N35.89545 E137.48670, bell) then come to a L fork (N35.89529 E137.48470) then a R fork just beyond a signboard with an excellent topo diagram. There is a nice view of a crater with a turquoise lake. The weather is good: warm with a few clouds above and below us but largely clear all day.

The upper hut complex is a short way further on with fancy steps leading up R to the summit area, with a building, another bell and several statues. The highest point (N35.89291 E137.48039, 3065m) is a rock outcrop R of the building, reached by a short easy scramble (YDS 2+). Passing L of the summit building a nice outcrop is reached, less cluttered and with a fine situation overlooking two craters; however it is lower. There are one or two survey markers although nothing looking like a proper triangulation point. Quite a few folk follow the path down here and head clockwise round the crater rim - looks pretty easy.

Adam and I reach the summit at 11:05 in 2hrs20 and leave at 11:45; the other four arrive a little while before we leave and they head down later, catching us at Station 7. We hike down to the cable car together, arriving at about 1400 (2hrs15 descent, similar to the ascent time due to my injured leg) then take a rather basic but tasty meal in the large restaurant before catching the 16:20 bus back to Akiso-fukushima. We take the train to Chino, planning to climb Aka-dake (Yatsuga-take) tomorrow.
