As of June 1, 2026, Karuizawa Town has introduced an Accommodation Tax. For Reservations made via IKYU, due to system limitations, the Accommodation Tax cannot be shown separately; therefore, our displayed prices have been revised to include the equivalent amount in advance. Meanwhile, Reservations made through our official website will be shown with a clear breakdown in the format “Accommodation Charge + Accommodation Tax.” Regardless of where you make your Reservation, no additional Accommodation Tax will be charged on-site, so you can stay with peace of mind at the displayed price only. We sincerely appreciate your continued patronage.
