A YAMAP activity record, published on 11 November 2026, describes a day on Tengu-iwa (天狗岩) and Eboshi-dake (烏帽子岳) in western Joshu, walked from the Ueno Village side. The activity title also appends the labels “Mitsuiwadake, Eboshidake.” The hike date itself is not stated separately from that page.
Recorded figures
The log gives:
- Time: 5 hours 59 minutes
- Rest: 33 minutes
- Distance: 18.6 km
- Ascent: 1,167 m
- Descent: 1,166 m
- Course constant: 32, rated strenuous (きつい), calculated from a standard time of 8 hours 46 minutes
The day total is given as 5 hours 59 minutes. The supplied text also lists passage times from 06:56 through 12:56, but without place names for those splits, so the individual checkpoints cannot be identified from this text.
How the day was set up
The hiker writes that an earlier idea of crossing from Ueno Village to the Nanmoku Village side, or the reverse, was dropped because the bus ran only on weekdays. This time they stayed at Shioji-no-Yu, having learned that lodging was possible and that the Okutano Line bus now runs there. An early start the next morning made an out-and-back from Ueno Village workable.
The ridge
There is a ridge route and a contouring route (巻道). On the way out they took the ridge: repeated ups and downs over rock peaks, described as typical of western Joshu and as a thrilling rocky traverse. The ridge is narrow, the right-hand side (the north side) drops away, and they moved carefully. Ropes and chains were largely absent.
From the ridge and the rock peaks, the view north was good. Farther off were Mt. Asama, Mt. Asama-kakushi, Mt. Haruna and Mt. Akagi; closer were Kanatake (鹿岳), Mt. Myogi and other rock peaks of western Joshu.
The weather is recorded as clear.
Access
Outbound, after the night at Shioji-no-Yu
- Nihon Chuo Bus, Okutano Line, Kannagawa-go: Shioji-no-Yu 6:50 to Ueno Village Fureai Hall 6:55.
- That section allows boarding and alighting between official stops, and they got off a little short of the hall.
Return
- The same bus: Ueno Village Fureai Hall 14:06, via Mamba, arriving Shinmachi Station at 16:35.
- Afternoon buses are noted at 14:00 and 16:00; the later one involves a one-hour transfer wait at Mamba.
- JR Takasaki Line: Shinmachi 16:38 to Akabane 18:08.
Notes on Shioji-no-Yu
The activity points to the facility site: Shioji-no-Yu. As written in the log:
- The water is described as colorless and odorless, pH 4.2, with no added water; heating, circulation and chlorine dosing are used. There is one large bath and one open-air bath.
- Day-use bathing is listed at 600 yen.
- Lodging is room only, about 5,000–7,000 yen. The lodging block is on higher ground in front of the bathhouse and is compared to a training-center dormitory.
- Self-catering is possible in the dining room; cooking utensils and a full set of tableware are provided.
- There is no convenience store, grocery or restaurant within walking distance, so bringing food is described as important.
- Meals are not included, but the onsen cafeteria can be used. The hiker found many dishes that use local ingredients worthwhile. Closing is early: last order 18:30, and earlier on days other than Saturday and in winter. Reserved boxed meals are also mentioned.
- Bathing at Shioji-no-Yu is unlimited while it is open, listed as until 20:00, and earlier on non-Saturdays and in winter. The lodging building has no bath, so a late arrival can mean no bathing.
Hours and prices above are as stated in the activity note, not a checked current timetable.
