Yahoo!トラベルユー... 2/22/2026Excellent access to nearby tourist attractions. The guidance and in-house services were excellent, and the staff provided kind and courteous assistance. The octopus shabu-shabu was absolutely delicious. The painting on the Room's sliding doors was very beautiful. Looking forward to staying again in the future!
