Company Outline

MYSTAYS HOTEL MANAGEMENT started out in July 1999 with the management and maintenance of weekly rental condominiums, then in 2005 entered the hotel industry with the “MYSTAYS” brand. Since then, we have expanded our business further to include hotel development and consulting, centered around outsourced operations. Now, as MYSTAYS Hotel Group, we operate more than 100 hotels all over Japan, from Hokkaido to Okinawa, offering various brands such as accommodation-specialized hotels, full-service urban hotels, resort hotels, hot spring resorts, and residence-type facilities with furniture and home appliances that can accommodate lodgers from one night to medium- and long-term stays.
