The loudest voice on Ikaho Onsen

I work at a ryokan in Ikaho Onsen. You've researched Ikaho well, and the video explains both the good things about it and the parts that are hard to hear for those of us on the ground. Let me add a few things, if I may. First, the water. The Golden Water is the old brown, cloudy water, and it warms you right through. The Silver Water, found in the Heisei era, is a colourless, transparent cold mineral spring; it is distributed to each ryokan and heated before it goes into the baths, and its soft quality is said to be good for the skin. And the remarkable part is that these two completely different waters rise from almost the same spot on the mountain behind Ikaho Shrine. The Golden Water is still governed by the komaguchi system, where the share is set by the width of the pipe, decided long ago, and it reflects the inherited rights of the old houses rather than the size of the business. Using more of it doesn't make your monthly charge rise in proportion either. So the old ryokan near the source use plenty of Golden Water whatever their size, and many of them don't use the Silver Water at all. Buying a new right to the Golden Water means paying a rights holder a very large sum, and mostly they won't sell in the first place, and the volume you get is small. The Silver Water, by contrast, is managed by Shibukawa City, which Ikaho belongs to, and you pay for what you use, so everyone can draw on it on equal terms. As for the newer ryokan away from the stone stairway, some cover everything with the Silver Water, and some have talked a rights holder into selling, laid a new pipe and now hold Golden Water of their own, less than the old houses but theirs. Most of those use the Silver Water alongside it to make up the volume they need. What you see a lot of lately is the big communal baths running both, and the open-air baths attached to guest rooms running Silver. For room baths the Silver Water is especially prized, because it's less likely to leave you light-headed and is safe for children, and because it throws off little mineral sediment, which makes it easier for guests to use and easier for the ryokan to run. On the stone stairway: until fairly recently there were a lot of group tours, so each ryokan kept its guests in with its own shop and its own evening dining, and the town emptied out little by little. There are still plenty of empty shops and empty ryokan, but new places have opened around the stairway, more guests walk it and more people come up just for the day, and a good deal of life has come back. Sorry for the length. Please do come to Ikaho at least once, whether you stay the night or come for the day.

伊香保温泉の旅館で働いている者です。 伊香保温泉についてよく調べられ、伊香保温泉について良いところも、現地の人間からすると耳が痛いところも分かりやすく解説されている動画でした。 勝手に情報を追加致します。 まず温泉の説明について、黄金の湯は古くからある茶色く濁った湯で、身体がよく温まります。一方、平成に発見された白銀の湯は無色透明の冷鉱泉で、各旅館に配られたのちに加温して提供されているもので、柔らかい泉質で肌に良いとされています。 そして驚くべきことに、この二つの全く異なる泉質の源泉は、ともに伊香保神社の奥にある山の、ほとんど似たような場所から湧出しております。 黄金の湯は相変わらず小間口制度により、旅館の経営規模というよりもむしろ老舗の既得権として、温泉管の太さによって昔から配分が決められております。そしてこれを多く使ったからといって、比例して毎月使用料が増えるものでもありません。 そのため、源泉近くに古くからある旅館はその規模に関わらず黄金の湯を豊富に使用し、白銀の湯は使わないというところも多いです。 黄金の湯の権利を新たに買い取るには非常に高い金額を小間口権者に支払う必要があり(そもそも中々売ってもらえない)、得られる量も少ないです。一方で白銀の湯については伊香保温泉がある渋川市が管理しており、使用量に応じて代金を支払うことで公平に使える形になっています。 石段街から離れた比較的新しい旅館はというと、白銀の湯により全ての温泉を賄っているところもあれば、小間口権者と話をつけ権利を買い取ることで温泉管を新設し、老舗に比べれば少ない量ではありながらも黄金の湯を所有している旅館もあります。その上で白銀も併用して、全体として必要な湯量を確保して運用している所が多いです。 最近よく見られるのは、大浴場は黄金白銀の併用、露天風呂付き客室に置くのは白銀、といった使われ方です。特に客室の露天風呂について、白銀の湯は湯あたりしにくくお子様にも安心であることや、湯の花が少ないことでお客様にも使いやすく、旅館も運用が比較的容易であることから、とても重宝されています。 また石段街についても、少し前までは団体旅行が多かったことから各旅館が施設内に売店や夜間の食事処を置くなどして囲い込みを行っていたため、徐々に街が廃れていました。 現在では空き店舗や空き旅館も多く残る一方、石段街を中心として新たなお店も増え、宿泊のお客様で石段街を散策される方や、外から日帰りで訪れる方も多くなり、随分と活気が戻ってきております。 長文となりましたが、ぜひ皆様一度は、宿泊なり日帰りなり、伊香保温泉へにお越しくださいませ。

  • Onogami Onsen CenterMurakami, Shibukawa, GunmaThe other day bath named in the thread as a better bet than the famous name, right by Onogami-Onsen station on the Agatsuma line. It was called Sachi no Yu until the operator changed and it became Hata no Yu.
