Hidden Onsen Near Nagoya: Aichi Has Exactly One "Real" Onsen, Japanese Bathers Say — and Name 20 More Baths
名古屋近郊の穴場温泉：地元民「愛知の本物の温泉は尾張温泉だけ」— それでも20湯超を実名で追加
By Rakutaro · Tokyo, Japan
Ask Aichi's onsen regulars about their own hot springs and the consensus is brutally honest: under a local geography channel's onsen rundown (145 comments), the verdict is that only one bath in the prefecture — Owari Onsen in Kanie — counts as a truly free-flowing onsen, and the top comment (71 likes) is a 40-year regular calling it a Shōwa-era time slip. Then the thread turns into a working map: commenters add more than 20 baths by name, from a business hotel in central Nagoya with its own hot-spring source to a weekends-only hidden spring deep in the mountains, and log closure reports on 8 baths — while half-joking that Aichi's real strength is super sento. Several would simply send you across the border instead.
“If your definition of a real onsen is "free-flowing, no recirculation," then calling anywhere here an onsen feels deeply wrong — except Owari Onsen. Honestly, Aichi has next to nothing you could call a genuine hot spring.”
温泉と名前が付いていても「循環無し」、「かけ流し」を本物の温泉とすると尾張温泉を除くとどこも温泉と呼ぶのは強い違和感があります。 やっぱり愛知は本物の温泉と呼べる温泉は皆無に等しいです。

Nagashima Onsen — ...ah wait, that's Mie.
長島温泉、あ、三重だった・・・

名古屋からだと長良川温泉がいいね〜
— @アモンファンンキー3 likesHonestly, instead of forcing yourself to hunt for an onsen in Aichi... isn't it quicker to just go to Gifu?

FAQ
- Are there any real onsen in Nagoya or Aichi?
- Commenters are blunt: by the strict definition — free-flowing, no recirculation — the comments' consensus is that Aichi has essentially one, Owari Onsen Tokai Center in Kanie (top comments at 71 and 37 likes). One local's advice for doubters: take them there. "That usually shuts them up" (21 likes).
- Can you take a hot-spring bath inside Nagoya city?
- Yes — commenters name Nagoya Crown Hotel, a business hotel with a bath fed by its own hot-spring source (47 likes), and Shiratori-no-yu, a true natural onsen in Minato ward (21 likes). Two station-adjacent bathhouses were reported closed as of the comments, so check a current map listing first.
- What is a super sento, and why do Aichi locals keep mentioning them?
- Super sento are large multi-bath day-spa complexes — and the consolation prize for the prefecture's thin natural-onsen scene. Aichi is called possibly "the strongest super sento region in Japan," and a Kasugai resident crowns Ryusenji-no-yu as the supreme pick (20 likes).
- Should you just go to Gifu or Mie for onsen instead?
- Several commenters say exactly that. From Nagoya they head to Nagaragawa Onsen in Gifu, Ikeda Onsen (one 40-year regular's Tokai best alongside Owari Onsen), or the big Nagashima spa resort next door — which, as one comment ruefully notes, is technically in Mie.

What Japanese visitors said — picked from the top 111 of 145 comments
As far as onsen towns go, Aichi kind of loses to neighboring Gifu and Mie — but for super sento, we might just be the strongest region in Japan.
温泉街としてはお隣の岐阜や三重に負けちゃう感のある愛知県ですがスーパー銭湯は日本最強の地域かもしれない
Owari Onsen has barely changed since my parents took me there as a kid, about 40 years ago. It feels like time-slipping back to the Shōwa era. This water and Ikeda Onsen over in Gifu are my personal best of the Tokai region.
尾張温泉は子供のころ親に連れてもらっていた時（約４０年前）から風呂の様子はほぼ変わってません。昭和にタイムスリップした気分になります。ここのお湯と岐阜の池田温泉が東海地方のマイベストです。
Owari Onsen. That horde of giant boulders — building that today would be brutal, in labor and cost. The water is hot by default, so I remember hunting for the cooler spots to get in. And it keeps you warm for a long, long time afterward.
尾張温泉。あの巨大な岩の大群。現代で建築したら、作業も費用も大変そう。 基本、熱いので、ぬるい場所を探して入った記憶。体感で、長時間ポカポカします。
Owari Onsen got seriously cleaned up in the renovation, but personally I loved the old vibe more. The entrance with the theater troupe's photos above the door, the bridge to the now-gone ryokan, the sealed-off staircase to the second floor, the women's clothing stall inside, that blue carpet... it was the best atmosphere.
尾張温泉はリニューアルで相当綺麗になったけど 個人的には昔のあの雰囲気のが好きだったなぁ 劇団の人の写真がドア上に飾られてる玄関 もうない旅館に続く橋 封鎖された2階への階段 婦人服売り場が併設されてる 青いカーペット 最高の雰囲気だった
Owari Onsen is so hot you can tell they don't add a drop of water.
尾張温泉加水していないってのがわかるくらいに熱いからね
Off the top of my head there are three missing. Shiratori-no-yu in Nagoya's Minato ward — sounds like a regular bathhouse, but it's a genuine natural onsen struck while they were building the foundations of a municipal parking lot. Yoshigo Onsen "Tahara Yunosato" in Tahara — it stopped advertising as an onsen and barely does public business now, so nobody notices it; these days it runs alongside a nursing home but still takes daytime bathers. And Yunoshima Onsen in Toyone — a hidden spring. Also, no super sento ever topped Dai-Nagoya Onsen. I want to soak in that again. If anyone around Nagoya tells you Aichi has no natural onsen, take them to Owari Onsen. That usually shuts them up.
私が知ってるだけでも3件紹介不足があるな。 天然温泉 白鳥の湯（名古屋市港区） 銭湯のような名前してるけど、市営駐車場の基礎を作ってた時に掘り当てた温泉を利用してる歴史は短いが正真正銘の天然温泉。 吉胡温泉 田原湯の里（田原市吉胡） 温泉としての広告をやめ、一般営業も細々なので一般人は気が付かない温泉。昔は普通の温泉施設だったが、現在は特別養護老人ホーム併設の温泉施設として日中の日帰り入浴が可能。 湯の島温泉（豊根村） 秘湯 スーパー銭湯だけど大名古屋温泉を超える温泉施設は無い。またあれに入りたい。 もし、名古屋市周辺の人で愛知県には天然温泉が無いと言うやつがいたら尾張温泉に連れていきましょう。大抵それで黙ります。
Nagoya Crown Hotel, right in the city — it's a business hotel, but it has a free-flowing onsen from its own source. It took care of me through plenty of work conferences and training stays.
名古屋市内にある名古屋クラウンホテルは、ビジネスホテルだが、源泉掛け流しの温泉がある。よく会議や研修でお世話になった。
Kasugai citizen here — there's no onsen anywhere near us, so Ryusenji-no-yu is the supreme option lol
付近に温泉が無いので竜泉寺の湯が至高な春日井市民ですw
Whenever I stayed at a business hotel in Nagoya, I'd head to a nearby bathhouse for dinner and a soak — such a shame that Taihei Onsen Tenpu-no-yu and Maruya Tama-no-yu, both conveniently close to the station, have closed down. And everywhere that's left has outsourced its dining to the same operator, so you end up eating the exact same menu as at every local bathhouse.
名古屋にビジホ泊まりすると、晩メシ＆風呂で近隣温泉行ってたけど、比較的駅チカで便利だった太平温泉天風の湯と丸屋玉の湯が閉館しちゃったのは残念だったなあ。ただ、どこも食事処がさぬき屋に委託に変わっちゃって、地元の風呂屋と同じようなメニュー食べる羽目になったなあ。
The ones I'd actually recommend to someone from outside the prefecture: Eiwa Onsen Misogi-no-yu, Gongitsune-no-yu, Sakai Onsen Yumotokan, and Owari Onsen Yumotokan. That's about it ♨️
永和温泉みそぎの湯，ごんぎつねの湯、坂井温泉湯本館、尾張温泉湯元館ぐらいが県外の人におすすめできる温泉♨️
No Yunoshima Onsen? That's Aichi's hidden gem among hidden gems. You said going around everything was too much, so I figured it would make the cut.
愛知の秘湯中の秘湯湯の島温泉がなかったな 全部周るのが大変とか言ってたから出ると思ったのに
Aren't you forgetting Yunoshima Onsen ♨️? In Toyone village? I got there via the San-en Nanshin Expressway, past Sakuma Dam, down Prefectural Road 1 — it is seriously far. Day-bathing only, and open weekends only.
湯の島温泉♨️忘れていませんか?豊根村にある温泉♨️ご存知無いですか?、私は三遠南信自動車道を通って佐久間ダムを通って県道一号線を通って行きました、めちゃくちゃ遠いです、日帰り温泉♨️で土日のみの営業です
I pop over to the Yuya Onsen foot bath all the time! Matsuya's gohei-mochi is a must too ❤
湯谷温泉の足湯にはちょこちょこ行ってますよ！まつやの五平餅もおすすめです❤
I heard Nishiura Onsen has run dry and they truck the hot-spring water in from somewhere else now 🤔
西浦温泉今は枯れて違う所から温泉運んで来てるって聞いたな🤔
Such a shame Dai-Nagoya Onsen closed down. There was no onsen as good as that one 😢
大名古屋温泉が閉業したのはとても残念。あんな良い温泉はなかった😢
