Ichikawa Annex Seikanso
Gunma Prefecture／Ikaho OnsenAn Onsen accommodation perched on the heights of Ikaho Onsen, featuring three private open-air baths.
At an altitude of 800m, spanning 15,000 tsubo of pristine nature. Flowers and plants showcase different appearances with each season. Our lodge, surrounded by lush greenery, blooms with beautiful flowers throughout the year. Experience the tranquility of Ikaho under the dappled sunlight.
On the day of my stay, I decided on a whim, got the Accommodation’s approval, and arrived after 8:00 p.m.When I told a man at the front desk that I was heading to a nearby izakaya for dinner, he cheerfully said, “Then please take this,” and gave me drink coupons for the place, lent me an umbrella, and even showed me a shortcut—always with a smile.It really put me at ease.The private bath was available until 11:00 p.m., so even though I arrived late I could relax and enjoy it. I also appreciated having a beer vending machine in the building.The property is old, but clean in an unpretentious way. The Room, futon bedding, and amenities all felt safe and comfortable to use. The other guests also seemed very considerate.Breakfast was great too—the main dish (grilled pork? hot pot?) went perfectly with rice and egg over rice.These days it’s rare, but everyone on staff I met appeared to be Japanese—maybe just by chance?Everyone provided such wonderful service that more than made up for the age of the building, and it was very comfortable throughout my stay.To be honest (and no offense meant), I only made a Reservation because there happened to be availability and didn’t expect much—maybe that’s why it felt even better.Next time I’d like to visit with dinner included.Thank you very much.
ずん太郎 8/22/2026This was my first time visiting Ikaho Onsen. The property we stayed at, Seikanso, has a long history, and while the Hotel does show its age, that gives it character and is a good thing. The Room had been renovated and was nice; however, the carpeted area by the window where the sofa is felt old, with a lingering human odor (aging-related smell) that seemed to have built up over many years. The sofa is also fabric-upholstered and had a similar smell, so we ventilated the Room whenever we returned. I understand that investing in upgrades can be difficult, but this part was disappointing. That said, the staff’s hospitality was excellent, and I am very grateful.

Introduction of the Accommodation
Breathtaking views from the expansive green grounds
Ikaho Onsen, the Ryokan Seikanso, is situated on a lush hilltop, offering panoramic views of Mount Akagi, the Tanigawa mountain range, and even the distant Nikko mountain range from its guest rooms. Within a 15,000-tsubo area of rich nature, we welcome you with seasonal open-air baths and stunning vistas.
Rooms with breathtaking panoramic views of Jōshū.
The open-air Onsen, Suiten-gu's Onsen, is a rare mountain-side open-air bath in Ikaho. While soaking in the Onsen amidst the natural forest, leaves gently flutter down.
Our cuisine uses "Mizuten-gu spring water" sourced from the mountain behind us. Additionally, we are committed to using ingredients from Gunma Prefecture and ensuring food safety as a "local production and consumption promotion store."
This accommodation features the only golf practice range in Ikaho Onsen (closed during winter). Additionally, within the premises of "Seikan Forest," there is a walking path leading to the Suiten-gu Hill.
