Amakazari-yama (雨飾山, 1,963 m) rises on the border of Nagano and Niigata prefectures, at the western edge of Myoko-Togakushi Renzan National Park. It is the western and highest peak of the Kubiki Mountains (頸城山塊), a Sea-of-Japan-side massif distinct from the Northern Alps. The mountain is famous for its twin summit — two close peaks nicknamed the "cat's ears" (猫の耳) — and for the "goddess's profile" (女神の横顔) silhouette its ridgeline forms when seen from below. Beech forest, lingering snow gullies into early summer, and an alpine flower meadow give the climb a strong Sea-of-Japan character.
Why Fukada Chose Amakazari-yama
Amakazari-yama is one of the hundred mountains in Kyuya Fukada's Nihon Hyakumeizan. The book is ordered roughly from north to south as a geographical sequence, not as a ranking, and Amakazari falls between Tanigawa-dake and Naeba-san in that order.
Fukada's chapter on Amakazari-yama is a personal one. He first tried to climb the mountain from the Otari side with the woman who would become his wife, but they were caught in heavy rain and stayed at a hot-spring inn in Otari without reaching the top. They finally succeeded together sixteen years after that first attempt. Of the mountain's twin peaks, Fukada wrote a fond line: "the left ear is my ear, the right ear is your precious ear."
The Mountain
| Item | Detail |
|---|---|
| Elevation | 1,963 m (6,440 ft) |
| Prefectures | Nagano / Niigata |
| Range | Kubiki Mountains (頸城山塊), Myoko-Togakushi Renzan National Park |
| Summit form | Twin peaks (双耳峰); South Peak holds the survey marker, North Peak holds stone Buddha statues |
| Book order | Roughly north-to-south, not a ranking |
| Typical season | July – October |
The summit splits into two close peaks. The South Peak carries the triangulation marker, and the North Peak is topped by stone Buddha statues. On a clear day the panorama reaches Hiuchi-yama and Yake-yama to the east, the Hakuba range and Northern Alps to the southwest, and the Sea of Japan with Sado Island to the north.
The name's origin is uncertain. One theory traces it to "Ama-yama" (アマ山), a place associated with praying for rain or to the heavens; another holds that the twin-peaked mountain was once called "Ryo-kazari-yama" (両飾山 / 両粧山), with the character 両 later becoming 雨.
The Routes
Otari-side Amakazari-Kogen trail (standard)
Grade: Challenging
- Character: The most popular route, starting from the Amakazari-Kogen trailhead on the Otari side. It climbs through beech forest, drops into and steeply climbs out of Aramugesawa (荒菅沢) — a gully that holds snow late into the season — and reaches Sasadaira (笹平), an alpine-flower meadow that blooms in July and offers the "goddess's profile" ridge view before the final climb to the twin summit.
Niigata-side Yakushi-one trail (from Amakazari-Sanso)
Grade: Challenging — steeper
- Distance: ~6.1 km one way (~12 km round trip)
- Elevation gain: ~1,110 m from the Amakazari-Sanso trailhead (~900–1,000 m)
- Time: ~3 h 40 min ascent, ~2 h 40 min descent
- Character: The steeper, shorter, less-trafficked alternative. It includes three fixed ladders (one roughly 4 m aluminium ladder and two roughly 2 m wooden ones) and a narrow ridge section with a steep drop-off on the right.
Getting There
Otari-side trailhead (Amakazari-Kogen):
Take the JR Oito Line to Minami-Otari (南小谷), then the Otari village bus about 40 minutes to Amakazari-Kogen (around ¥840, several departures per day).
Niigata-side trailhead (Amakazari-Sanso):
From JR Itoigawa, take the Itoigawa bus (Nechi line) toward the Yamaguchi stop, the access point for the Amakazari-Sanso trailhead.
There is no mandatory private-vehicle regulation on either trailhead, so a rental car is also an option.
Mountain Huts
Amakazari-Sanso (雨飾山荘): A historic hut at the Niigata-side trailhead, founded in 1880 (Meiji 13), with an open-air hot spring known as Miyako-wasure-no-yu (都忘れの湯).
Otari side: Amakazari-so (雨飾荘) lodging sits near the Amakazari-Kogen trailhead, alongside a free campground and parking (around 70 cars) open from mid-June to the end of October.
Flora and Wildlife
Asiatic black bears (ツキノワグマ): Asiatic black bears inhabit the beech-forest zone on this Honshu mountain. Bear-awareness gear, including a bear bell, is sensible advice for this terrain.
Beech forest and alpine flowers: The lower and middle slopes pass through buna (beech) forest with a strong Sea-of-Japan character. The Sasadaira meadow blooms with alpine flowers in July.
Seasonal Guide
June: Significant lingering snow persists into early-to-mid June, especially in the gully just below Sasadaira and on the north-facing Yakushi ridge. The route is rated harder during this残雪期 (lingering-snow period), and beginners are advised to wait until July.
July: The Sasadaira meadow comes into flower; generally the more accessible start of the season.
August: Summer hiking season.
September – October: Autumn conditions on a Sea-of-Japan-side mountain.
Practical Tips for Foreign Visitors
Plan around the snow. If you are visiting in June, be aware that snow gullies and north-facing slopes may still require care and experience. July onward is the safer window for less-experienced hikers.
Know which trailhead you want. The Otari-side Amakazari-Kogen trail is the popular standard route with the signature Aramugesawa and Sasadaira landmarks. The Niigata-side Yakushi-one trail from Amakazari-Sanso is shorter and steeper, with fixed ladders and an exposed ridge.
Public transport works here. Both trailheads are reachable by train plus a local bus, so a car is not strictly required.
Frequently Asked Questions
Is Amakazari-yama a day hike or an overnight?
It is normally climbed as a day hike. The Niigata-side Yakushi-one trail runs about 6.1 km one way (~12 km round trip), with roughly 3 h 40 min up and 2 h 40 min down. Lodging sits at the base of both trailheads if you would rather stay the night before.
Can I reach the trailheads without a car?
Yes. For the Otari-side Amakazari-Kogen trailhead, take the JR Oito Line to Minami-Otari, then the Otari village bus about 40 minutes (around ¥840). For the Niigata-side Amakazari-Sanso trailhead, take the Itoigawa bus (Nechi line) from JR Itoigawa toward the Yamaguchi stop. There is no mandatory private-vehicle regulation on either side, so a rental car also works.
When is the best season, and when does the snow clear?
July through October is the typical season. Significant snow lingers into early-to-mid June, especially in the gully just below Sasadaira and on the north-facing Yakushi ridge, which makes the route harder during the lingering-snow period. The Sasadaira meadow comes into flower in July, generally the more accessible start of the season.
Are there bears on the mountain?
Yes. Asiatic black bears (ツキノワグマ) inhabit the beech-forest zone on this Honshu mountain. Carrying bear-awareness gear, including a bear bell, is sensible advice for this terrain.
Is Amakazari-yama suitable for beginners?
Both routes are rated challenging. The Yakushi-one trail includes three fixed ladders and a narrow ridge with a steep drop-off, while the Otari route's crux is the steep climb out of Aramugesawa. Beginners are advised to wait until July, once the lingering snow has cleared.
