Trek : Kori St. -> Mt.Akakuna > Mt.Sobatsubu ->Sengen Pass -> Urayamaguchi St.

I walked up Mt Sobatsubu (h=1473m) at 1st June. The distance from Kori Station of JR Ome line to Urayamaguchi Station of Chichibu railway was 31.4km. It took me over 10 hours walk. Today, I have a little knee pain from this afternoon, not this morning. It was a fine weather and I had nice meets in this trekking.
My trekking path and mountain profile of yesterday's is shown at the next From_kori_to_urayamaguchi picture. 


I rode on the train from Kawagoe Station that arrived at 7:40am Haijima Station, the transfer time at Hijima was little, but a platform was very crowded with people to transfer because of weekday. The train for Okutama was 7:42am at the next platform.
I got on the intended train. But, I thought that I should have been checked a relation between train door and platform stairs. Or I should have boarded on the 2nd train at Kawagoe Station.
Next dash of transfer was at the Ome Station. The time was only 1 minutes but on the same platform. Please memorize, the train to Okutama from Ome is shorter about two vehicles. I arrived at Kori Station 8:28am.

JR Kori Station  --> starts 8:30am
There is a crossover that connect to the North Exit, is placed ahead on a platform. It's a good short cut to the North Exit. When you need a lavatory, that is on the South Exit of the platform.

This is the South Exit of Kori Station. The lavatory is on the left of this

This is the entrance of the mountain path to Mt.Akakuna and Mt.Kawanori. So the guide post is written in Japanese language "赤久奈山を経て川乗山へ登山口". It means that "This is a start of a trail up to Mt.Kawanori, via Mt.Akakuna."

notes: Mt.Akakuna = 赤久奈山 = 赤杭山,

After Mt.Akakuna, a new detour route has been set on the mountain path. Last time when I walked was building. New guide post was set on the breakaway point.

<- Over there, that is Mt.Kawanori (川苔山).

Mt.Kawanori -> Odoridaira
At this point, I walked to Mt.Sobatsubu (蕎麦粒山) , not to Mt.Kawanori.

I walked to Mt.Sobatsubu (蕎麦粒山).

Odoridaira -> Mt.Sobatsubu
Dsc_3919s 11:33)  At this point, I selected a detour route of Mt.Sobatsubu so as to walk to Urayamaguchi Station and keep away my physical energy consumption as much as possible.

Dsc_3920s I was misunderstanding that Ippaimizu(一杯水) is placed on the North of my destination. So I was almost lost a right route because of the sign indication "一杯水" Ippaimizu.

~13:00)  I kept walking from Kori Station without break about five hours, so I got a cramp in the calf. I had to make a break, I drank a water a lot and took a lunch. About 10 minutes later, my physical condition was getting better. I felt the importance of water ingestion and adequate rests.

13:49)  After I wDsc_3933salked up from the guidepost, I met a person who was walking up on the ridgeway of Toriyato-one(鳥屋戸尾根) from Mt.Shonoiwa. We talked about the locational situation and the destination each other for a while. She was walking to Mt.Sobatsubu. The ridgeway of Toriyato was not found on my GPS map, and I misused the compass. So I had started a wrong route walking. We checked the map and our location about ten minutes. It made us a good communication each other. If I haDsc_3935sd not met her at that place, I was walking a wrong route for a while. I walked up to Mt.Sobatsubu and Sengen Pass (about h=800m) with her. She was about 10 years elder, but tough and looked young. I thought she is very cool woman. When I walked up to Mt.Sobatsubu with her, she climbed up by faster speed for me, so I came near to feel a cramp in the calf again. I heard from her regarding the quick treatment for a cramp in the calf by Chinese herbal medicine. She said she always carries the medicine Shakuyakukanzoto (芍薬甘草湯) in the envisioned emergencies of cramp in the calf on the mountain trail.
Dsc_3936s Dsc_3938s 14:10)  I arrived at the summit of Mt.Sobatsubu.

14:26)  I arrived at the breakaway signpost to Sengen Pass (仙元峠). We walked apart each from this point.
Dsc_3944s Dsc_3945s 14:34) I arrived at Sengen Pass

Sengen Pass (仙元峠) ->
Dainichido (
This route was very complicated and tricky. The directing post was few. It was a miracle thing that I could come to Dainichido. I arrived at Dainichido 16:17.
