  • Milky White Hot Spring Amid Fresh Green Maple Leaves

    I woke up to rain, and in the morning open-air bath, the wet green maple leaves were glistening. Maybe I drank a little too much and ate too much yesterday? Time passed slowly, and I felt truly refreshed. What soothed me most was the smiles of the front desk team and the staff at Banri. Thank you very much.

  • The Onsen is excellent.

    Whenever I think of an Onsen, this is the place I choose lately.They offer a variety of Rooms—Japanese-style, Japanese-Western, and this time a Western-style Room—so I enjoy experiencing the differences each stay.I would love to visit again. Regarding the meals at Banri, they felt a little lightly seasoned. I understand you can’t make them stronger for everyone’s taste, so I would appreciate it if you could provide salt and pepper on the table.
