*As of December 2025, based on our company's research. Calculated based on publicly available information regarding hotel room counts in each region.

In recent years, especially during the plum rain season, there has been growing interest in 'staycation-style travel' that is less affected by weather, and travel styles that emphasize the in-hotel experience itself. Instead of packing in travel and sightseeing, the enrichment of indoor activities at the accommodation is becoming an important factor in choosing a hotel.

Responding to these needs, Accor's domestic hotels offer a variety of stay experiences, such as reading, art, wellness experiences, and family-friendly activities, where the time spent at the hotel itself can be enjoyed as the purpose of the trip, rather than just moving around.
