8. Common Complaints
While reviews are overwhelmingly positive, some recurring points of feedback include:
- Remote Location: The property's secluded setting, while contributing to its tranquility, can be seen as a downside for travelers who prefer to be closer to bustling attractions or public transport options without relying on a shuttle. However, the complimentary shuttle service largely mitigates this.
- Hot Spring Temperature: Some guests have noted that the temperature of the private hot spring baths can be quite high, leading some to prefer the public bath facilities.
- Pricing: The luxurious nature of the property naturally comes with a higher price tag, which might be a consideration for budget-conscious travelers.
- Children Policy: Sengokubara COCON generally welcomes children aged six and older, with specific "Family Days" designated for younger children or when booking the entire guest house. This policy might be a limitation for families with very young children planning a stay outside these designated times.
- Accessibility: The facility is not universally designed, lacking an elevator in its three-story structure, which could be an issue for guests with mobility challenges.
- Traditional vs. Modern: For guests expecting strictly traditional Japanese ryokan accommodations, it's noted that Sengokubara COCON offers a blend of Western comforts and Japanese surroundings.

Although we didn't stay in this hotel when we were cancelled on by a neighbouring hotel the stuff kindly helped us order a taxi to a different hotel and helped us with our luggage. So kind, thank you Cocon team!

I really wanted to visit because of the high ratings on Google Maps and YouTube. The location and environment are great, with no tourist attractions nearby, so it's recommended for those just staying overnight. Of course, you can go sightseeing from there by car, but don't worry! 😊😊 The hotel is so luxurious that it would be a shame not to spend more time at the hotel. With a glimpse of Mt. Fuj...
