Dear Jimmy Hi! This is Hotel Fukinomori. The hotel`s onsens are separated by a gender. But we do also have private bath in our hotel as well. It is 2,000 yen for 70 minutes and we do have only fixed schedule; 15:30 pm, 17:00 pm, 20:30 pm, or 22:00 p.m. If you are comfortable with the price and still interesting to book the bath, please e-mail us. Again, thank you so much for your e-mail and looking forward to hear from you. Best Regards, Fukinomori

Dear Jessica Thank you so for your e-mail. If you are planning to stay in this Kiso area for three night, it is totally up to your next destination. If you want to get relax first and do the hike, we recommend stay at our hotel in advance and do the hiking next. But in case if you want to do the hiking first, then we recommend do the Nakasendo hiking first then come to our hotel and stay and get relax. But in our hotel we do also have shuttle bus service, so in case if you want to catch a train the next day, we recommend to stay at our hotel and use the shuttle bus service then catch a train at Nagiso station. Again, thank you so much for the question. In case if you have any other questions, please feel free to contact us anytime. Best Regards, hotel Fukinomori
