Tsurugi-dake (剱岳, 2,999 m) stops one metre short of 3,000 — and shrugs at it. This peak in the Northern Alps trades round numbers for the most serious hiking in the Hyakumeizan: roughly a dozen fixed-chain and ladder sections, a vertical chain called the Kani-no-Tatebai, a one-way traverse called the Kani-no-Yokobai, and a summit that holds a 1,300-year-old story of mountain ascetics. By general consensus among Japanese alpinists, it is the hardest of the hundred famous mountains that can still be climbed without ropes or technical gear. It is also the one that kills hikers most years. This guide is for deciding whether — and how — you should attempt it.
Not the Shikoku mountain. This is Tsurugi-dake (剱岳) in Toyama, on the mainland Northern Alps — a 2,999 m chained scramble. It is often confused in English with Tsurugi-san (剣山) in Tokushima, Shikoku — a gentle 1,955 m peak with a chairlift, covered in our separate Tsurugi-san guide. If you came looking for an easy day hike with a lift, you want the other one.
How hard is it, really?
Why Fukada Chose Tsurugi-dake
Kyūya Fukada paired Tsurugi with its great neighbour across the range: if Hotaka is the venerable elder presiding over the southern Northern Alps, he wrote, then Tsurugi is the brilliant young prodigy of the north. What drew him was the quality of the terrain — every step above the Tsurugisawa basin demands attention — and the mountain's extraordinary history.
In 1907, an Imperial Land Survey team led by Shibasaki Yoshitarō fought its way to the summit to plant a triangulation marker. There they found, lodged in the rock, an iron sword and the head of a Buddhist pilgrim's staff (shakujō-tō), dated to roughly the Nara–Heian period — proof that mountain ascetics had stood on this "unclimbable" summit more than a thousand years earlier. The survey's "first ascent" had to be rewritten by over a millennium. The original shakujō-tō, an Important Cultural Property, is now held in Toyama Prefecture (the Tateyama Museum), not in Tokyo.
That survey expedition became the 2009 film Tsurugidake: Point of Heaven (劔岳 点の記), based on Jirō Nitta's novel — a national hit that introduced the mountain to a generation who had never thought of climbing.
The Mountain
| Elevation | 2,999 m (9,839 ft) |
| Prefecture | Toyama |
| Range | Northern Alps (Hida Mountains) |
| Summit character | Exposed rock ridge; ~13 fixed chain / ladder sections |
| Hyakumeizan | Included (book order is roughly north-to-south, not a ranking) |
| Difficulty | Hardest of the Hyakumeizan for non-technical hikers |
| Typical season | Late June – late September (snow lingers into early July) |
Tsurugi rises above the Tsurugisawa (剱沢) basin, a glacially carved bowl that holds snow year-round, and is reached from the Tateyama–Kurobe Alpine Route. There is no easy way up: every approach involves either sustained chained scrambling or a brutal amount of climbing.
The Routes
Two routes reach the summit. Almost everyone takes the first.
| Route | Start | Character |
|---|---|---|
| Bessan-one (別山尾根) — standard | Murodo (2,450 m), via the Alpine Route | The chains. ~13 fixed sections; Kani-no-Tatebai & Yokobai. 2 days from a hut. |
| Hayatsuki-one (早月尾根) | Banbajima (馬場島, ~760 m) | ~2,200 m of climbing — one of Japan's most grueling ridges. Fit, experienced only. |
Standard: Bessan-one (別山尾根) from Murodo
Grade: Strenuous — the most serious non-technical route in the Hyakumeizan
The approach itself is one of Japan's great journeys: the Tateyama–Kurobe Alpine Route, a chain of cable cars and highland buses across the mountains, delivers you to Murodo (2,450 m).
- Day 1 — Murodo → Tsurugisawa (~3–4 hours): A paved walk past the Mikuriga-ike ponds, then up over the Betsuzan-noricoshi col (別山乗越, ~2,750 m) and down into the Tsurugisawa basin. Significant elevation is lost here that you regain the next day. Overnight at Kenzansō or Tsurugisawa-goya.
- Day 2 — Summit and back (~7–9 hours round trip): From the hut the trail climbs onto the Bessan ridge and turns into a chained scramble. The numbered sections build steadily; near the top comes the Kani-no-Tatebai — a vertical chain pitch, ascent only. The descent uses a separate line including the Kani-no-Yokobai, a horizontal traverse where footholds are out of sight below you. The summit is a small platform with a sword monument (a replica; the original artifacts are in Toyama).
The up and down routes are deliberately separated at the crux to keep traffic one-way. Do not climb against the flow, and never pass another hiker on a chain.
Alternative: Hayatsuki-one (早月尾根) from Banbajima
Grade: Strenuous / expert — extreme sustained ascent
From Banbajima (馬場島, ~760 m), the Hayatsuki ridge climbs over 2,200 m to the summit in one unrelenting line — routinely cited among Japan's hardest ridge ascents. Hayatsuki-goya (早月小屋, ~2,200 m) breaks the climb, and the upper section has its own chains that join the standard route near the top. This is for fit, experienced hikers who want the mountain without the Alpine Route crowds — not a first option.
Getting There
The standard route starts at Murodo, on the Tateyama–Kurobe Alpine Route.
From Toyama: Toyama Station → Tateyama Station (Toyama Chihō Railway, ~1 hour, ~¥1,230) → Tateyama Cable Car to Bijodaira (7 min) → Highland Bus to Murodo (~50 min, 2,450 m). Roughly ¥3,700 one way for the cable car + bus leg.
From Tokyo: Hokuriku Shinkansen to Toyama (~2 h 10 m, ~¥12,000 reserved), then as above.
From Nagoya: JR Limited Express Hida or via Kanazawa to Toyama (~3 hours total), then as above.
Hayatsuki route: Banbajima is reached by car or taxi from Kamiichi / Toyama; there is no convenient public bus, which is part of why this side stays quiet.
Important: the Alpine Route is seasonal (mid-April to late November). Full crossing tickets can be booked online (English available) at alpen-route.com/en and are strongly recommended in peak season. The 20 m snow walls at Murodo in April–May are a famous sight — but that is sightseeing season, well before Tsurugi is climbable.
Mountain Huts
| Hut | Elevation | Use / note |
|---|---|---|
| Kenzansō (剣山荘) | ~2,470 m | Closest base to the Bessan-one climb; ~¥13,000–15,000 (2 meals) |
| Tsurugisawa-goya (剱沢小屋) | ~2,520 m | Basin hut with a large campsite alongside; ~¥13,000–15,000 |
| Tsurugigozen-goya (剱御前小舎) | ~2,750 m | On the col between Murodo and Tsurugisawa |
| Hayatsuki-goya (早月小屋) | ~2,200 m | The only break on the Hayatsuki ridge |
Reserve ahead for July–August; carry cash. The Tsurugisawa campsite is one of the great tent sites in the Alps, with the peak filling the view.
The Chains: What to Expect
The reputation rests on the upper Bessan ridge.
- Sections: roughly 13 numbered chain and ladder pitches, from a few metres to around 30 m, increasing in seriousness toward the summit.
- Kani-no-Tatebai (カニのタテバイ): the signature pitch — a near-vertical chain climbed on the ascent only.
- Kani-no-Yokobai (カニのヨコバイ): a horizontal traverse on the descent, where the first foothold is below your line of sight. This is where nerves count most.
- Rock: generally good rough granite with solid holds on the main line; the danger is exposure and other people, not crumbling rock.
- Traffic: in peak season the chains queue. The descent is harder than the ascent — most accidents happen coming down, tired, in deteriorating weather.
Flora and Wildlife
Japanese rock ptarmigan (raichō, ライチョウ): Tsurugi's high ridges and the Murodo plateau are among Japan's best ptarmigan ground. A Special Natural Monument, grey-brown in summer and white in winter, often unbothered by hikers — move slowly and give them space. Walk the Jigokudani / Mikuriga-ike area at Murodo early for the best chance before you even start the climb.
Alpine flowers: the Tsurugisawa basin is exceptional in July–August — chinguruma with its feathery seed heads, Tateyama-rindō (Tateyama gentian), and alpine sedges across the rocky ground. The season is short and intense.
Asiatic black bears (tsukinowaguma, ツキノワグマ): this is Honshu, so the species is the Asiatic black bear, not the Hokkaido brown bear. They live in the forested lower zones around Bijodaira and the Banbajima approach; on the high alpine route encounters are rare. Carry a bear bell for the forest sections.
Seasonal Guide
- Late June – July: snow lingers in gullies; crampons sometimes needed in early July. Wildflowers at their best in Tsurugisawa.
- August: peak crowds and chain queues. Huts full — book well ahead. Afternoon thunderstorms common; start before dawn.
- September: usually the best conditions; autumn colour from mid-month; fewer people than August.
- October: trails close progressively; first real snow from mid-month. Not an objective after that.
Practical Tips for Foreign Visitors
- Treat weather as the gate, not the summit. Tsurugi has no good bad-weather day. If the forecast for summit morning is wet or windy, stay in the basin — a night at Tsurugisawa is a fine trip on its own.
- A helmet is expected here, unlike most Hyakumeizan — rockfall kicked loose by hikers above is the real hazard. Rentals are available at the huts (~¥500/day); accept the cost.
- Two days, not one (from Murodo). Stage at Kenzansō or Tsurugisawa and climb in the cool early morning before the chains queue.
- Consider a guide if the exposure worries you. Local JMGA guides run Tsurugi trips (and the Alpine Route is worth a day regardless of whether you summit).
- Watch the film first. Tsurugidake: Point of Heaven adds real context; the summit sword monument is the tangible link to that 1907 story.
