  • This was my repeat stay.This time I stayed in the “Tasogare” Room, and its calm atmosphere allowed me to truly relax.As someone who enjoys alcohol, the all-inclusive plan—where I can enjoy my favorite drinks without worrying about extra charges—is a major highlight unique to this Accommodation. Because you can take your time without watching the clock, it’s easy to end up staying longer than planned.Also, compared with my previous visit, there were more types of games available to bring into the Room, which could be great when staying with two or more people.The private sauna I look forward to every time also came with a full 90 minutes—plenty of time—and I really appreciated being able to use it at my own pace without worrying about others. After the sauna, I could unwind in the lobby, my Room, or the lounge, making for a truly luxurious experience.All of the staff were courteous and warm, and I felt comfortable throughout my stay. Even as a returning guest, it was nice to be treated with consistent kindness.If I had one small note: the slope leading down to the parking area is a bit steep, so drivers of low-clearance cars or those not confident behind the wheel may need to be cautious. That said, it seems unavoidable given the location.Overall, I was very satisfied again this time. I’d love to return in another season. Thank you very much.

  • The Room is compact, but it has a wonderful free-flowing Onsen bath, available anytime. The meals are thoughtfully prepared and truly delicious—I feel this place is top-tier in its class. The staff work very hard and are genuinely kind, and I was pleasantly surprised that the complimentary wine was Japanese. I visited shortly after the renovation some time ago, and compared to then, the building’s decor now feels much more settled and well integrated. I think it’s an Accommodation where you can relax at ease—whether traveling alone or as a pair—and really enjoy your stay. After a long stretch of being busy with work, I came for an easy break; there is also a sauna, and I was able to unwind deeply and felt better physically afterward, which I truly appreciated. Not necessarily in comparison with other places, but there was no reason to deduct any stars, so this is my rating.

    [Notice] Mold Removal and Anti-Mold Treatment Completed in All Guestroom Bathrooms

    Thank you very much for your continued support of SEN Yugawara.

    We have received many comments from guests regarding mold in the bathrooms of our guestrooms. We sincerely apologize for any discomfort this may have caused.

    Due to the hot and humid conditions typical of an Onsen area, as well as the building’s structure that tends to trap moisture, it had been difficult to fully prevent mold through daily cleaning alone.

    From June 15 to 18, 2026, we carried out mold removal in all guestroom bathrooms and applied a professional anti-mold treatment to help prevent recurrence. At the same time, we also performed disassembly cleaning of ventilation fans and removed mold from curtains and other items.

    We will continue to strengthen our daily cleaning and ventilation management to provide a comfortable environment for all guests. Thank you for your continued patronage of SEN Yugawara.
