1. Nishimuraya Honkan (Kinosaki Onsen, Hyōgo)

During our recent trip to the Kansai region, we stayed at Nishimuraya Honkan, which was recently awarded two Michelin stars for accommodations. They also operate a sister ryokan nearby called Nishimuraya Shogetsutei, which is just a 7–8-minute walk away. Nishimuraya Honkan only accepts guests aged 10 and above and has a limited number of rooms, making it ideal for a quiet and refined experience. If you're traveling with younger children, Shogetsutei would be a more family-friendly option.

The rooms at Honkan are beautifully traditional, with stunning garden views right outside the window. There are two small but charming onsen baths on-site, and guests are welcome to use the larger public baths at Shogetsutei. One of the highlights of Kinosaki Onsen is that as long as you stay at any local ryokan and pay the onsen usage fee, you can access six public bathhouses scattered throughout the town.

Our stay included both kaiseki dinner and breakfast. Dinner was a multi-course seasonal feast, and breakfast offered both Japanese and Western options. From the presentation and ingredients to the flavors and service, every meal was flawless. The staff were exceptionally attentive—whether it was the host who welcomed us or the dinner attendants, everyone explained the dishes and answered all our questions with great care.

Getting to Kinosaki Onsen is easy from Osaka or Kyoto via direct JR trains, which take about 2 hours and 40 minutes. Be sure to reserve your seats in advance. Upon arrival at Kinosaki Onsen Station, there were staff on-site helping guests find their ryokan’s shuttle service.

We booked directly through the official website, and the staff contacted us by email beforehand to confirm allergy info, dinner time, and transfer arrangements.

Although Kinosaki is not as famous as places like Hakone or Kusatsu, it's a hidden gem with a peaceful atmosphere, kind locals, and fewer crowds.

Tip: The visitor center across from the station offers luggage storage and bicycle rentals—perfect for exploring the area at your own pace.
