The historic Mampei Hotel in Karuizawa will temporarily close from January 2023 to undergo an 18-month restoration and refurbishment. It is scheduled to re-open in 2024 to mark its 130-year anniversary.

The historic hotel first opened in 1894 as the Kameya Hotel. It was one of the leading western-style hotels. It is famously known as the destination of choice for John Lennon and Yoko Ono when they spent their summers holidaying in Karuizawa. 

The main Alps building is wooden and was built in 1936. It has reached a point where large-scale repairs and additional reinforcements are required to the structure in order to expand its lifespan. The other concrete buildings will also be extended and refurbished.

The 109-room hotel is operated by Mori Trust.
