  • This time, I stayed at Ichibokaku with my mother and sister. The moment we got out of the car in the parking lot, we could smell sulfur, which made us feel like we had truly arrived at an Onsen. The Hotel had a slightly old-fashioned feel, but the staff at the front desk were incredibly kind and welcoming. The Room also had a nostalgic Onsen Ryokan vibe, which was very relaxing and pleasant. The meals offered a wide variety of dishes, including international cuisine, all of which were delicious. The baths included both an open-air bath and a large public bath located in different areas, which added to the excitement. It was such a wonderful Onsen experience. I would love to visit Ichibokaku again someday.Thank you for making it such an enjoyable trip!
