Sales of flagship properties started in September 2021, and sales have exceeded 4 billion yen from the starting year. NOT A HOTEL is developing its business with a constantly innovative approach, such as starting sales of the right to use as NFTs in August 2022. NOT A HOTEL AOSHIMA was completed in November 2022, and NOT A HOTEL NASU in December of the same year, and together started operation.

Through this investment, KDDI supports the business growth of NOT A HOTEL, a developer with a vision of "making the world more exciting." Through collaborative efforts with the KDDI Group, KDDI will assist in increasing and expanding NOT A HOTEL's purchase channels and means, thereby aiming to increase the number of owners.
