Akita Prefecture／SenbokuA hidden property where you can fully experience the rich local culture of Akita, including the Akita Kanto Festival, private onsen with natural spring water, and local ingredients.
Located in the Tazawako Mizusawa Onsenkyo, this hidden Property with only 10 rooms offers an experience of the Tohoku Big Three Festival, the "Akita Kanto Festival."

Immerse yourself in the charm of Akita's changing seasons and the warm hospitality unique to this hidden Property for a truly relaxing experience.
I visited twice last year and stayed at Aoani Sanso again this time. I booked during the lowest-priced period, but the owner said the meals are the same even at a lower rate, and they were very delicious. I’d like to stay again in autumn. Kind and attentive service—an excellent Accommodation.
Yahoo!トラベルユー... 4/8/2026This was our third stay, and it truly is a wonderful Onsen Accommodation. We used the private Onsen three times in total. The meals had a casual pub-style atmosphere, which was very relaxing. The prosciutto we ordered separately was delicious. My wife also asked me to bring her back again. Thank you very much.
