가이노사와 온센은 1979년 아키타시 교외 다이헤이산 기슭에 문을 연 온천 료칸입니다. 매분 200리터, 62.5도의 나트륨 염화물천을 물을 타거나 데우지 않고 원천 그대로 흘려보내며, 대욕장·노천탕·숙박객 전용 욕장을 갖추고 있습니다. 객실은 6조와 8조 화실 총 15실로, 2016년에 단차를 줄인 배리어프리 구조로 새로 지었습니다. 식사는 아키타 브랜드 소와 현지 식재료를 쓴 가이세키 요리와 매일 바뀌는 가정 요리 중에서 고를 수 있습니다. 선대 사장이 약 40년에 걸쳐 가꾼 넓은 삼림 정원에서 사계절 산책을 즐길 수 있습니다.
