Enjoy a private stay at this “secluded hot spring Accommodation for adults,” nestled in the Ikaho mountain range. All 8 Rooms feature an open-air bath.

Our Accommodation is a hot-spring inn for guests aged 20 and over. In the early Meiji era, the 14th-generation proprietor, Yoshishige Fukuda, opened a new annex in Ikaho, Joshu—“Oku Ikaho Ryotei Kaichoro”—distinct in character from the family’s long-established Accommodation. In “Kaichoro,” “Kai” signifies tranquility, and “Cho” expresses our wish for guests to spend their time at ease; with this hope, we chose the name. From our carefully crafted cuisine to refined traditional Japanese-style Rooms and high-grade Rooms with an emphasis on design, all Rooms feature a private open-air bath. We also offer a spa and reservable private open-air baths, so you can fully enjoy your stay.

  • This time, we booked a Multiple Night Stay again in the same guest room we stayed in previously: a garden open-air Onsen bath room (15-tatami main room + 4.5-tatami tea room). For impressions of the Room itself, please refer to my comments from last year.First, I’d like to share how wonderful a Multiple Night Stay is.1) The cuisine is outstanding. As introduced on the website, the monthly menu is crafted into a course using seasonal ingredients of that month, with careful attention to presentation and tableware. That alone is excellent, but the Multiple Night Stay menus are an even more diverse lineup—an explosion of the head chef’s creativity using seasonal ingredients. Both dinner and breakfast feature menus that are almost entirely different from the monthly offerings. Truly worthy of a master artisan.2) You can enjoy the open-air Onsen freely. Although it’s an in-room open-air Onsen bath, with only one night your time to enjoy it feels limited. With a Multiple Night Stay—especially on the second day—you have much more time for the open-air Onsen and can fully relax and enjoy it.3) Perfect for sightseeing in Ikaho. With a Multiple Night Stay you need to leave your Room during cleaning, but if you go sightseeing in Ikaho there’s no issue at all. If you head out toward the stone steps street from Fukuichi’s side, you’ll be right below Ikaho Shrine. The shrine is close by, and from there it’s easy to find your way for a round trip to Kajika Bridge as well. The Ikaho Ropeway is also comfortable to reach—it feels like going slightly downhill from the shrine area—and on your way back you can rejoin the stone steps around the middle and enjoy various shops as you walk back up toward Fukuichi.Next, I’d like to express my gratitude for the wonderful service during our stay. The attendant who served us at dinner on our first night was someone who had also taken care of us during our previous visit. In addition to being surprised with having a Multiple Night Stay menu served on day one, she carefully explained each dish as well as three coordinated alcoholic beverages selected for pairing. I’m truly grateful, and I would love to request her again next time.From breakfast on day two onward, our attendant was also serving as Kayokoro’s sommelier. At dinner on day two, when I asked on the spot for sake that would pair well with large turban shell caught off Ito off Izu Peninsula (Daesazae), he recommended Isojiman—an excellent match for the food. He told me he studied hard and earned his sommelier qualification; very impressive indeed. I was also surprised that his name is almost identical to mine; I hope he continues thriving as Kayokoro’s sommelier.We requested Shuttle Service both ways this time, and both drivers provided calm driving along with courteous assistance when getting in and out of the vehicle—thank you very much.After checkout as well, thank you sincerely to staff who continued carrying our heavy luggage and guided us on our way out.This has gotten long, but our Multiple Night Stay at Kayokoro was simply superb—we definitely want another Multiple Night Stay next time too.

  • I stayed here with my elderly parents.We requested smaller portions in advance, and the amount was perfect. We usually end up leaving some, but we finished everything. Every dish was carefully prepared, and the tableware was lovely. It was truly delicious.The Onsen in our Room was also wonderful, and my parents enjoyed it many times.The staff were very courteous and thoughtful in many ways. Thank you very much.We would love to visit again!

  • A lingering, deep finish of Daiei turban shell, like fishing lights glowing in a white bowl.

    [Hazuki–Nagatsuki] Dish of the Month

    Even in the mountain valleys of Ikaho, late summer lingers gently in Hazuki (August).
    While the day still holds its warmth, the evening breeze softens,
    and our menu begins to take on a cool fragrance and the calm of early autumn.

    To begin your meal, we offer gifts from the sea delivered from Ishinomaki, Miyagi.
    The smooth sweetness of sea urchin, the delicate melt of milt, and the subtle savor of pike conger.
    With a hint of sesame vinegar, this dish lets you enjoy a lingering ocean finish beneath its refreshing chill.

    Our hassun is a colorful assortment that reflects both summer’s lingering presence and autumn’s first arrival.
    Greens, vermilion tones, and soft whites brighten the plate—each bite revealing a different seasonal expression.

    Paired with today’s seasonal sashimi is “Kuyō Masamune Junmai Daiginjo” from Kumamoto.
    A grapefruit-like aroma and a crisp acidity that complements summer seafood with ease.
    A pure, light sake crafted from polished Yamada Nishiki rice.

    And this month’s quietly captivating highlight is our warm dish.
    We prepare large turban shell from off the coast of Ito in Izu as Isaribi-yaki (fisherman’s fire-grilled style).
    Its roasted aroma, a whisper of rocky shore air, and deep umami that grows with every bite—
    a dish that feels like a softly lit summer night sea within the bowl.

    As you begin to sense the next season beyond the heat,
    please take your time savoring these cool lingering notes at Kaichoro in Hazuki (August).
