Kagawa Onsen Guide

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

香川のおすすめ温泉地・温泉宿・日帰り温泉を厳選紹介。

Kagawa is Japan's smallest prefecture, but it holds two of Shikoku's most significant cultural sites: Konpira-san (Kotohira-gu Shrine), the legendary pilgrimage shrine with 785 stone steps to the main hall, and Ritsurin Garden in Takamatsu, a 400-year-old Tokugawa-era daimyo garden awarded three stars by the Michelin Green Guide Japan. Konpira Onsen-go forms the gateway to the pilgrimage. Shionoe Onsen, in the mountains south of Takamatsu, was reportedly founded by Kobo Daishi (founder of Shingon Buddhism). Shodoshima Island in the Inland Sea offers olive-grove onsen retreats. The prefecture's defining food — Sanuki udon — is the most consumed local food in Japan, with 700+ udon shops. From Okayama: 50 min by JR across the Seto Ohashi Bridge.

香川県は日本で最も小さな県ですが、四国屈指の文化遺産を2つ擁します:こんぴらさん(金刀比羅宮)——785段の石段を登る伝説の参拝霊地——と栗林公園(高松、400年の大名庭園、ミシュラン・グリーンガイド三つ星の特別名勝)。こんぴら温泉郷は参拝の玄関口、塩江温泉は高松南の山あいで空海(弘法大師)開湯と伝わります。瀬戸内海の小豆島はオリーブ畑の温泉リゾート。県の代表料理「讃岐うどん」は日本で最も消費される地方食で、県内に700軒以上のうどん店。岡山から瀬戸大橋経由JRで50分。

Konpira Onsen-go is the historic ryokan district at the base of "Konpira-san" — formally Kotohira-gu Shrine — one of Japan's most revered pilgrimage destinations. The shrine perches on Mt. Zozu, reached via a famous 785-step approach (1,368 steps including the inner shrine). Pilgrims have stayed here for centuries; today about 30 traditional ryokan and modern hotels operate. The hot springs were developed in 1997 from deep drilling. Combined with the 1835 wooden "Kanamaru-za" — Japan's oldest surviving kabuki theater — and the historic shop-lined approach (omotesando) leading up the steps, Konpira makes a uniquely complete cultural-onsen visit. From Takamatsu: 1h by JR.

Insider Tips for Kagawa

Know before you go

香川の旅で知っておきたい5つのこと

Konpira 785 Steps — Bring Water + Time

こんぴらさん785段、水と時間に余裕を

The 785-step climb to Kotohira-gu's main shrine takes 45–60 min one-way at moderate pace. The further 583-step climb to the inner shrine ("Okusha") takes 60+ more min. Total round-trip 2–4 hours. Wear comfortable shoes, bring water (vending machines along the way), and consider visiting in cool morning (8–10am). Walking sticks (¥500 rental) help. December is icy and dangerous.

金刀比羅宮本宮までの785段は中等ペースで片道45〜60分、奥社までさらに583段の60分以上。往復2〜4時間。歩きやすい靴、水持参(自販機あり)、涼しい朝(8〜10時)推奨。杖レンタル(500円)あると便利。12月は凍って危険。

Sanuki Udon Pilgrimage Tour

讃岐うどんピルグリム巡礼

Kagawa has 700+ udon shops — the highest density per capita in Japan. "Udon Pilgrimage" (うどん巡礼) is an established travel mode. Top picks: "Udon Honjin Yamada-ya" (Mure, near Yashima — kamaage udon in a registered-cultural-property mansion), "Hinode Seimenjo" (Sakaide — a noodle factory serving udon only 11:30am–12:30pm), and "Osada in Kanoka" (Zentsuji, near Konpira — celebrated kamaage udon). Most shops open from early morning to mid-afternoon only — udon is breakfast/lunch food. ¥250–¥600 per bowl.

香川には700軒以上のうどん店——人口比で日本一の密集度。「うどん巡礼」が確立した旅行形式。代表店:「うどん本陣 山田家」(高松市牟礼町、屋島近く、登録有形文化財の屋敷で釜揚げうどん)、「日の出製麺所」(坂出市、11:30〜12:30の1時間のみ店頭提供)、「長田in香の香」(善通寺市、こんぴら近く、釜あげうどんの名店)。多くは早朝〜昼過ぎのみ営業——うどんは朝食・昼食の食べ物。1杯250〜600円。

Setouchi Art Triangle from Aji or Naoshima

瀬戸内アートトライアングル巡り

The "Setouchi Art Festival" (Setouchi Triennale, held every 3 years) showcases art across 12 Inland Sea islands. Even off-festival years, the permanent collections at Naoshima (Chichu, Benesse, Lee Ufan), Teshima (Teshima Art Museum — single-room oval space with water installation), and Inujima (Inujima Seirensho — old copper refinery turned art space) are world-class. Allow 3 days for all three.

「瀬戸内国際芸術祭」(3年に1度のトリエンナーレ)は12の瀬戸内海の島で展開。閉幕年も常設展:直島(地中・ベネッセ・李禹煥)、豊島(豊島美術館——卵型の水のインスタレーション)、犬島(犬島精錬所——旧銅精錬所のアート空間)はすべて世界級。全部周るのに3日。

Kanamaru-za Old Kabuki Theater

金丸座、現存最古の歌舞伎芝居小屋

"Konpira O-Shibai" — the spring kabuki performance at Kanamaru-za — happens annually in April, with major Edo-style productions in the 1835 wooden theater.

Shodoshima Olive Park

小豆島オリーブ公園

Shodoshima's "Olive Park" (free) offers 2,000+ olive trees, the iconic Greek-style "Olive Windmill" photo spot (a "Magic Witch Broom" rental for ¥100 makes the famous Instagram photo), olive product shop, and the "Olive Memorial Hall." Combined with the day-use onsen at the park (¥500), it makes a perfect 4-hour day stop. Best months: October (harvest), May (white blooms).

小豆島「オリーブ公園」(無料)は2000本以上のオリーブの木、象徴的なギリシャ風「オリーブ風車」撮影スポット(「魔女の宅急便」風レンタル100円で有名なインスタ写真)、オリーブ商品店、「オリーブ記念館」。公園内日帰り湯(500円)と組合せて4時間の半日コース。最適月:10月(収穫)、5月(白い花)。

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 Kagawa 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

Konpira-san — how physically demanding is it?こんぴらさん、体力的にどう?

The 785 steps to the main shrine are achievable for most physically able adults — many seniors complete it with rest stops. Pace yourself; allow 60–90 min round-trip plus rest. The inner shrine (additional 583 steps) is much steeper and harder, only ~10% of pilgrims attempt it. Wheelchair access via taxi up the back route is possible to a partial point.

本宮までの785段は健康な大人ならほぼ全員可能——多くの高齢者も休憩しつつ完登。ゆっくりペースで休憩込み60〜90分。奥社(追加583段)は急峻で難しく、参拝者の約10%のみ挑戦。車椅子は裏ルートからタクシーで途中まで可能。

Best base for Naoshima art island visit?直島アート訪問の拠点はどこ?

For dedicated art focus: stay on Naoshima itself (Benesse House Hotel is most acclaimed but limited rooms; alternatively several small inns). For more flexibility + onsen: stay at Aji Onsen (40 min ferry to Naoshima) or Takamatsu City. Day-trips from Okayama (via Uno Port, 20 min ferry) also work but you'll miss the evening atmosphere on the island.

アート集中ならNaoshima島内泊(ベネッセハウスホテル最有名、客室限定。他に小さな旅館数軒)。柔軟性+温泉なら庵治温泉(直島まで船40分)か高松市内。岡山(宇野港から船20分)からの日帰りも可能だが島の夕方の雰囲気を見逃す。

How to reach Kagawa from Tokyo?東京から香川までのアクセス?

Fastest: Tokyo (Haneda) → Takamatsu Airport, 1h 20min, then 40 min by bus to Takamatsu City. Train option: Shinkansen Tokyo → Okayama (3h 15min) + Limited Express Marine Liner across the Seto Ohashi Bridge to Takamatsu (1h). Bridge view is itself a highlight. Total by train: 4h 30min.

最速:羽田→高松空港1時間20分のフライト+バス40分で高松市内。鉄道:東京→新幹線で岡山(3時間15分)+特急マリンライナーで瀬戸大橋を渡って高松(1時間)。瀬戸大橋ビューが見どころ。鉄道合計4時間30分。
