Toyama · Kurobe Gorge Onsen + Tateyama Alps / 富山 / 黒部峡谷の秘湯と立山連峰

Toyama Onsen Guide

Top hot springs, ryokan, and day-use baths in Toyama — bilingual guide for travelers.

富山のおすすめ温泉地・温泉宿・日帰り温泉を厳選紹介。

Toyama's onsen culture is shaped by two geographic forces: the Northern Alps (Tateyama range) rising from the Sea of Japan within 30 km of shore, and the Kurobe Gorge — Japan's deepest V-shaped valley, cutting north from the alpine ridge to the coast. Unazuki Onsen serves as the gateway to the legendary Kurobe Gorge Railway (an open-sided trolley train carved into the cliffs in 1937). The deeper Kuronagi, Kanetsuri, and Babadani onsen are accessible only by this train — true "hikyo" hidden hot springs. Himi on the Sea of Japan offers winter "kanburi" (cold-yellowtail) cuisine with Tateyama-view baths. From Tokyo: 2h 10min via Hokuriku Shinkansen.

富山の温泉文化は二つの地理によって形成されました。海岸からわずか30kmで3000m級の立山連峰がそびえる劇的地形と、その尾根から海岸へ刻まれた日本一深いV字渓谷・黒部峡谷です。宇奈月温泉は1937年開業の崖を縫う名物トロッコ「黒部峡谷鉄道」の玄関口。さらに奥の黒薙・鐘釣・祖母谷温泉はこのトロッコでしか行けない「秘境温泉」の世界。日本海側の氷見温泉郷は寒鰤(かんぶり)料理と立山ビューが名物。東京から北陸新幹線で2時間10分。

Unazuki is the largest onsen town in Toyama and the operational base for the Kurobe Gorge Railway — a converted construction-trolley line built in 1937 to carry workers building Japan's most ambitious hydroelectric dam. The 1h 20min one-way ride through 41 tunnels and 22 bridges, mostly with open-sided carriages, is one of Japan's most thrilling scenic train experiences. Unazuki's spring water is piped 7 km from Kuronagi Onsen upstream — exceptionally pure alkaline simple water. Modern ryokan and hotels line the Kurobe River. From Tokyo: Hokuriku Shinkansen to Kurobe-Unazuki Onsen station, then 25 min by local train.

  • Gateway to Kurobe Gorge Railway — Japan's top scenic trolley

Kuronagi is one of Japan's most legendary "hikyo" (hidden hot springs) — a single ryokan deep in the Kurobe Gorge, reached only by the Kurobe Gorge Railway (alighting at Kuronagi Station) and a 20-minute mountain trail (June–November only). Its large riverside open-air bath is one of the most photographed onsen vistas in Japan, with the Kurobe River roaring just a meter away. The 96°C spring also supplies Unazuki Onsen downstream via one of Japan's longest hot spring pipelines. The single ryokan (Kuronagi-yu Ryokan) has welcomed bathers since 1868. No same-day day-use during peak season — reservations essential.

  • One of Japan's most legendary "hidden onsen"
  • Riverside open-air bath, river just 1 m away
  • Only accessible via Kurobe Gorge Railway (Jun–Nov)

Note: Closed in winter (December–May). Kurobe Gorge Railway typically operates mid-April to late November.冬期休業(12〜5月)。黒部峡谷鉄道は4月中旬〜11月下旬の営業。

Himi is a fishing town on Toyama Bay famous for two things: "kanburi" — the winter yellowtail (buri) caught in the cold Toyama Bay that has been called "Japan's finest" since Edo times — and the dramatic view of the Tateyama alpine range rising 3,000m above the bay on clear winter mornings. The "Tateyama Across the Sea" view — 3,000m mountains rising directly above the sea — is a rare sight worldwide, often likened to Mt. Cook in New Zealand. Himi Onsen-go was developed in the 1990s along the coast, with ryokan offering both views and seafood-rich kaiseki. From Kanazawa: about 1h by Shinkansen to Shin-Takaoka, then the JR line via Takaoka.

  • "Tateyama Across the Sea" — 3,000m mountains over the bay
  • Winter "kanburi" yellowtail — Edo-era "Japan's finest"
  • A world-rare view: 3,000m peaks directly above the sea

Kanetaro Onsen is one of Toyama's most recognized destination hotels — a single sprawling resort property in the foothills of the Tateyama Alps, named after the legendary boy-hero "Kintaro." The defining feature is the enormous "Ryujin no Yu" stone-built open-air bath, with views toward the 3,000m Tateyama peaks. Its water composition (sodium-calcium chloride-sulfate-sulfur) is unusual even within Japan. Open since 1971, the property includes multiple bath complexes, restaurants, and is family-friendly. From Toyama Station: 30 min by Toyama Chiho Railway + free pickup.

  • Massive "Ryujin no Yu" stone open-air bath — Tateyama view
  • Unusual complex chemistry (chloride + sulfate + sulfur)
  • Named after the folk hero Kintaro

Shogawa is a quieter onsen district along the wild Shogawa River in southwest Toyama, framed by deep mountain ridges. The signature experience is the Shogawa Gorge Sightseeing Boat — a 30-min cruise through a steep-sided dammed reservoir that's spectacular in foliage season. The sulfate-type springs feed several riverside ryokan, and the gorge's most famous bath — Omaki Onsen — can be reached only by the sightseeing boat. 30 min upstream lies Gokayama — the smaller, less-touristed UNESCO World Heritage village of "gassho-zukuri" steep-thatched farmhouses (Shirakawa-go's sister site). From Shin-Takaoka Station: 25 min by bus.

  • Shogawa Gorge sightseeing boat — 30-min canyon cruise
  • Gateway to Gokayama UNESCO gassho-zukuri village

Insider Tips for Toyama

Know before you go

富山の旅で知っておきたい5つのこと

Kurobe Gorge Trolley — Book Tickets 1 Month Ahead

黒部峡谷トロッコは1ヶ月前予約

The Kurobe Gorge Railway runs mid-April to late November only — and the famous October-November foliage trains book completely 1 month ahead. Get the "Window Car" upgrade (¥1,200 extra) for enclosed seating in cold/rain weather. The "Special Open Car" is unbeatable in good weather. Round trip ~2h 40min.

黒部峡谷鉄道は4月中旬〜11月下旬の運行のみ。10〜11月の紅葉トロッコは1ヶ月前完売。雨や寒い日は「窓付き車両」(追加1200円)を、好天時はオープンの「特別車両」が最高。往復2時間40分。

Himi Kanburi Yellowtail — December–February Only

氷見の寒鰤は12〜2月限定

"Kanburi" (cold yellowtail) is the result of buri caught during Dec–Feb in cold Toyama Bay — fat content peaks at this time, making the flesh almost beef-like in richness. Many Himi ryokan offer "kanburi kaiseki" only in this 3-month window. Mid-January is peak. Book 2–3 months ahead.

「寒鰤」は12〜2月の冷たい富山湾で獲れる鰤で、脂のりがピーク(牛肉のような濃厚さ)。氷見の旅館は冬の3ヶ月限定で「寒鰤会席」を提供。1月中旬が最盛期。2〜3ヶ月前予約推奨。

Tateyama Alpine Route in Late April

立山黒部アルペンルートは4月下旬がベスト

The Tateyama Kurobe Alpine Route opens mid-April with the famous "Snow Wall" (Yuki no Otani) — 15m-tall walls of snow on either side of a cleared road, only visible until early June. Combine with Unazuki Onsen (1 night) + alpine route day trip + Kurobe Dam viewing. Reserve a 2-day "Alpine Ticket" online before arrival.

立山黒部アルペンルートは4月中旬開通、名物「雪の大谷」(高さ15mの雪壁)は6月初旬まで限定。宇奈月温泉1泊+アルペンルート日帰り+黒部ダム見学が王道3日プラン。「アルペンチケット」2日券を事前にオンライン予約推奨。

Shogawa + Gokayama Loop

庄川温泉郷+五箇山セット

Gokayama UNESCO World Heritage village (gassho-zukuri thatched farmhouses, sister site of Shirakawa-go) is 30 min upstream from Shogawa Onsen. Day-trip from your ryokan: morning visit to Gokayama (~3h), afternoon Shogawa Gorge boat (~30 min), evening onsen + dinner. Far less crowded than Shirakawa-go.

五箇山(世界遺産・合掌造り集落、白川郷の姉妹)は庄川温泉郷から30分上流。旅館を拠点に:朝に五箇山訪問(3h程)、午後に庄川峡遊覧船(30分)、夜は温泉+夕食。白川郷より遥かに観光客少なく落ち着いた雰囲気。

Toyama Black Ramen + Hotaru-ika

富山ブラックラーメン+ホタルイカ

Toyama has two food cultures you must try: "Toyama Black" ramen (jet-black soy-pork-shoyu broth, originally made for postwar workers needing salt to replace sweat) and "hotaru-ika" (firefly squid, March–May only — Toyama Bay's endemic 7cm glowing squid, served boiled or as sashimi). Ryokan dinners rarely include them — eat in town.

富山名物の二大グルメ:「富山ブラックラーメン」(戦後労働者の塩分補給のため作られた漆黒の醤油豚骨)と「ホタルイカ」(3〜5月限定、富山湾固有の7cm発光イカ、ボイル or 刺身)。旅館の夕食には出ないことが多いので街中で。

Travel Essentials

Plan your trip

旅の準備

Book a Ryokan

Use major Japanese travel platforms to find ryokan with private open-air baths, tattoo-friendly facilities, or vegan kaiseki meals.

eSIM & WiFi

Most onsen towns have spotty 4G coverage. A Japan eSIM or pocket WiFi keeps Google Maps and translation apps running smoothly.

Getting There

See each onsen listing above for access details. Most Toyama onsen towns are reachable by JR trains, limited express, or highway bus; for remote springs, a rental car gives the most flexibility.

FAQ

Common questions

よくある質問

How accessible is Toyama from Tokyo?東京から富山までのアクセスは?

Excellent — Hokuriku Shinkansen "Kagayaki" from Tokyo Station reaches Toyama in 2h 10min, the next stop Kurobe-Unazuki Onsen in 2h 25min. Direct daily service every 30 min. Many onsen ryokan offer free shuttle pickup from the Shinkansen station — confirm before booking.

東京から北陸新幹線「かがやき」で富山駅まで2時間10分、次駅・黒部宇奈月温泉駅まで2時間25分の好アクセス。30分毎の運行。多くの温泉旅館が新幹線駅から無料送迎を提供。予約時に確認を。

Is the Kurobe Gorge train scary?黒部峡谷トロッコは怖い?

It moves slowly (~25 km/h) and the views are dramatic but safe — guardrails throughout, no sudden drops within the train. Some sections cross high bridges with steep gorge views. Speed is gentle enough for children. The biggest issue is COLD — even summer mornings can require a jacket in the open-sided cars.

速度はゆっくり(時速25km)で景色は壮大ですが安全。手摺は完備、車内に急な落下はありません。一部は高い橋を渡り渓谷を見下ろします。子供でも問題なし。最大の課題は寒さ——夏でも朝はジャケットが必要。

Best season for Toyama onsen?富山温泉のベストシーズンは?

October (Kurobe Gorge foliage at its peak — book 2 months ahead) and late January (Himi kanburi yellowtail + clear winter views of "Tateyama Across the Sea"). April–May for the Tateyama Alpine Route Snow Wall. Avoid August (humid heat).

10月(黒部峡谷紅葉のピーク、2ヶ月前予約推奨)と1月下旬(氷見の寒鰤+海越し立山連峰の冬の絶景)がベスト。4〜5月は立山アルペンルートの雪の大谷。8月の蒸し暑さは避ける。
