Everthing Fumi has described about the house is 100% accurated.
Kamiuma area is not crowded of tourists, it is quite and safe. There are big supermarket, convenient stores and nice restaurants along the 4-min walk from station to the house.
Fumi is really a super host, very kind and always gives lots of useful info.
The house is spacious, clean, bright, well-designed and comfortable for 6 people with fully equipped kitchen and bathroom, especially when 2 toilet rooms are hard to find.
This property is absolutely one of the best in Airbnb listings. Highly recommended.
