Thanks for asking! So you'd have to check directly with them to be sure (soraniwa-hotel.jp/en), but unfortunately I don't believe the rotenburo can be booked privately. However, their sister hotel next door (livejapan.com/en/in-kansai/in-pref-kyoto/in-gion_kawaramachi_kiyomizu-dera-temple/spot-lj0039689/) seems to have a private rotenburo in each room - and great views as well. Might be an option. Hope this helps!
