Snowy 100 Famous Mountain, Mt. Azumaya in Nagano and Gunma Prefectures

Hello cave critters.

Had enough snow yet this year? I was hip deep the other day. It was great.

For my 81st (and probably) last hike of the year, I dropped by Mt. Azumaya for my second time. I was hoping to catch good weather since my last visit was marred by rain.

I was denied clear skies again. I will have to go a 3rd time, I guess.

. . . about Mt. Azumaya

It is most commonly known as Mt. Azumaya, 四阿山 but also Agatsuma, 吾妻山.

This 2,354-meter mountain is on Yuya Fukada's list of 100 Famous Mountains.

This is a dormant stratovolcano that is on the prefectural boundary between Nagano and Gunma.

Elevation: Lowest: 1,455 m Highest: 2,354 m Total Ascent: 1,153 m Total Descent: 1,153 m

Technical considerations/difficulty:

It's steep, as you would expect.

On this particular day, I was wearing chain spikes. For the most part, this was perfect. The snow was hip deep in places but, for the most part, the trail had already been walked on by enough people that I didn't sink it. I did have snowshoes with me, but didn't find them necessary for the most part. The only area I did think about putting on the snowshoes was the few hundred meters on either side of Mt. Neko. That peak had had less traffic, and I kept sinking into the snow. It is above the treeline there, and the wind was biting so I didn't want to stop to put on the snowshoes.

As I recall, the only ropes were on the descent from Mt. Neko.

Facilities:

Nothing on the trail. There is a restroom and some kind of store near the trailhead that are open during the summer months.

Thoughts/observations/recommendations:

I really want to get here on a clear day.

(Along with all the regular stuff such as maps, headlamps, boots, feet, and brains, . . .) don't forget:

I can't think of anything special for this mountain. As general advice for hiking in winter, I recommend spare gloves and hats in case you drop something on the trail. Always have dry socks. Also, I think packing snowshoes and poles, just in case is a good idea.

Let's look at some pictures, shall we?

This parking lot is ¥300 and is about 15 minutes down the road from the trailhead. There is a parking lot up there, too, but it's not open in winter.

If you come by bus, you have to start hella far below this point.

Nice views early on. If only it were crystal clear.

I like the trail.

. . . and in August . . .

The top

This is what it looks like in August.

Thanks to the trail being packed down a bit I didn't need my snowshoes. Spikes were enough.

It got quite blustery between Azumaya and Nekodake. There is a saddle barren of trees between them and the wind whips over it. This part of the trail isn't trafficked too much, so I sank in up to my waist a few times. Because of the wind, I didn't want to stop and put on my snowshoes. I just had to slog through it for a half hour or so.

There's me mug. Isn't that a face only a mother could love?

Sugadaira has a bunch of ski areas. It bills itself as a sort of Swiss resort. The places have names like Davos.

Merry Christmas and Happy New Year.

Happy Hanukkah, if that's your thing.

And to all, a joyous festivus with much airing of grievances and great feats of strength.

See you in 2026.

Thank you for your attention to this matter.

Mt. Takabocchi and Mt. Hachibuse. Snowscape and sunset.

Hello, everyone.

This is a report on a rather long hike I made. There was just enough snow to make the scenery beautiful, but not enough to make it difficult or dangerous.

The skies were clear, and I could see for dozens of miles in every direction of the compass.

It was late enough that I was able to catch the sunset from a peak with an unobstructed view.

Great day

. . . about Mt. Hachibuse

Nice mountain in Matsumoto City, Nagano. To its west lie the wide valley in which Azumino and Matsumoto Cities lie, with Kamikochi and the Northern Alps beyond. It offers spectacular views of Lake Suwa, Mt. Fuji, Yatsugatake, and Utsukushigahara as well.
