Mt. Daibosatsurei Day Hike | A Beginner-Friendly Loop from Kamihikawa Pass over the Karamatsu Ridge to Daibosatsu Pass, with the Best Mt. Fuji View I've Had

2024.12.15

If you want to climb one of Japan's 100 Famous Mountains for the views without it being an ordeal, the one I'd recommend without hesitation is Mt. Daibosatsurei (2,057 m) in Yamanashi Prefecture. The loop from Kamihikawa Pass has almost no dangerous rock or chain sections, and the ridge gives you a full panorama of Mt. Fuji.

We walked it in December, in early winter. It was around 1°C in the morning and cold enough at the summit that the sign was encased in ice — but that same cold made the air so clear that we got what I'd call the most beautiful view of Mt. Fuji I've had on any mountain.

Below: the flow of the loop from Kamihikawa Pass over the Karamatsu Ridge, Kaminari-iwa, the summit and Daibosatsu Pass, plus timings, winter clothing and what to look out for, written for people newer to this. There's aerial footage of the ridge and Fuji in the video too, which is worth seeing.

Route overview (day loop from Kamihikawa Pass)

• Area: The Daibosatsu range, Koshu City, Yamanashi Prefecture
• Highest peak: Daibosatsurei (2,057 m), one of Japan's 100 Famous Mountains
• Route (loop): Kamihikawa Pass → Fukuchan-so → Karamatsu Ridge → Kaminari-iwa → Daibosatsurei summit → Kaminari-iwa → the ridge → Daibosatsu Pass → Fukuchan-so → Kamihikawa Pass
• Walking time: About 4–5 hours excluding breaks
• Access: By car, use the car park at Kamihikawa Pass. By public transport, take the seasonal bus to Kamihikawa Pass from Kai-Yamato Station on the JR Chuo Main Line
• Difficulty: ★★☆☆☆ (beginner). The only sustained steep climbing is part of the Karamatsu Ridge, and there are essentially no dangerous chain sections

Daibosatsurei is popular as a first 100 Famous Mountain, and for good reason. You can drive or take a bus up to Kamihikawa Pass at about 1,580 m, which cuts the height you actually have to climb dramatically and puts the ridge views within reach even if you're not confident about your fitness.

Starting from Kamihikawa Pass — into clear morning air

We set off at 8 a.m. from Kamihikawa Pass. Lodge Chobei stands right by the car park and marks the trailhead. Shortly after starting there's a split between the trail and the road; I took the trail, wanting the atmosphere.

A December morning up there is properly cold — around 1°C. But once we started walking, the clear air and the frost glittering on everything were beautiful enough that I forgot about it. My pack that day was 6 kg, about a kilo lighter than usual, since this is a shorter loop of roughly five hours.

One thing to note: in winter the huts up here can close on an irregular schedule. I assumed that might be the case and carried a proper meal with me. If you're going in winter, don't count on the huts — bring extra food and water.

Fukuchan-so, and how I layered for early winter

About 30 minutes of gentle climbing from Kamihikawa Pass brings you to Fukuchan-so, the junction where the Karamatsu Ridge route splits from the direct route to Daibosatsu Pass.

Since we're here, let me run through what I wore. Early winter is a tricky one to judge, so I hope it helps.

• Base layer: Montbell merino wool (Montbell is Japan's best-known outdoor brand)
• Mid layer: Montbell Wickron long sleeve (their quick-drying synthetic)
• Outer: Mammut shell
• Bottoms: Montbell merino wool leggings plus mid-weight trousers
• Accessories: Gloves and hat all Montbell, shoes by Merrell
• A spare lightweight outer layer in the pack (the three layers above were enough on the day)

Even at around 1°C you'll work up a light sweat climbing. Early-winter mountains are hot when you move and cold when you stop, so layers you can add and remove quickly are the way not to get this wrong. We left the junction at 8:55, expecting about an hour to the next landmark, Kaminari-iwa, and reached the Karamatsu Ridge aiming for 10 o'clock.

Up the Karamatsu Ridge to Kaminari-iwa

Past Fukuchan-so, the Karamatsu Ridge is the one stretch of sustained climbing on this loop. It starts as zigzags through trees with no view, so this is where you put the work in. It isn't long, though — settle your breathing and take it step by step and you'll be fine.

Then the trees end, the view opens, and you pop out onto the ridge at Kaminari-iwa. In clear winter air the distant ranges were astonishingly sharp. From here the hard climbing is basically done and the rest of the day is the reward.

The summit of Daibosatsurei (2,057 m)

It's only a short climb from Kaminari-iwa to the summit. In the shade, though, there was still mud and ice, so we moved carefully.

The summit of Daibosatsurei (2,057 m) is surrounded by trees and has no view. It's a slight surprise for the high point of a famous mountain, but the scenery on this one is all on the ridge that follows. The summit sign was thickly coated in ice, like someone's sculpture. We admired that for a moment — you only get that in winter — touched the marker and turned back.

To Daibosatsu Pass — Mt. Fuji and the whole ridge

Back at Kaminari-iwa for a short rest, and then the highlight: the ridge walk to Daibosatsu Pass. I'd decided in advance not to watch the clock on this section and just take it in.

Past Kaminari-iwa, turn around and Mt. Fuji is right there to your right. And on that day it was as clear and as beautiful as I've ever seen it from any mountain — visible all the way down to the base of its slopes, and genuinely imposing. I stopped walking repeatedly. From the air, the scale of the ridge and Fuji together comes across even more strongly, so do watch the drone footage in the video.

It isn't only Fuji, either. From the ridge you can see Mt. Kaikomagatake, Mt. Norikura and the Yatsugatake range. Following the open ridge eventually brings you to Daibosatsu Pass (1,897 m), where the Kaizan-so hut sits and plenty of hikers stop to rest. From there we descended toward Fukuchan-so and closed the loop back at Kamihikawa Pass.

Difficulty, access, and winter cautions

To gather the practical points in one place:

• Difficulty: Beginner-friendly. The only sustained climb is part of the Karamatsu Ridge, and there are essentially no dangerous chain sections. Because you can drive or bus up to Kamihikawa Pass, the height gain is modest.
• Access: By car, start from the Kamihikawa Pass car park. By public transport, the seasonal bus from Kai-Yamato Station on the JR Chuo Main Line is convenient. In winter, road conditions to the pass and bus operations can change, so always check in advance.
• Winter footing: Ice and mud linger near the summit. Chain spikes or similar traction devices are worth carrying.
• Warmth and food: The ridge wind is cold and drops the felt temperature sharply. A windproof outer, gloves and a hat are essential. As above, huts may be closed at irregular times in winter, so carry plenty of food, water and snacks.

For context on how we film: we work as a two-person team, presenter and camera operator, including the aerial shots of the ridge and Mt. Fuji. When we fly a drone, we check the rules and confirm the area permits it first.

Final thoughts: climb this one if you love Mt. Fuji

Daibosatsurei lives up to its reputation. Few difficult sections, safe enough for a beginner, and yet the moment you reach the ridge you get the kind of panorama a famous mountain is famous for. That balance of accessibility and scenery explains the popularity entirely.

Above all, if you love Mt. Fuji, this is the one. I've never seen it more clearly from anywhere else, and the scale of it was beyond what I can put into words.

A clear winter day is your best chance at sharp views of Fuji and the ranges beyond. Sort out your warm layers and your traction, and go and meet the best Mt. Fuji you've seen from the ridge of Daibosatsurei.
