Hoshino Resorts (Karuizawa, Nagano Prefecture, CEO: Yoshiharu Hoshino), which operates 71 facilities in Japan and overseas with the theme of making travel more enjoyable, has focused on the new travel trend “Coolcation” (*1), which is spreading in Europe and the United States, where people “spend their vacations in cool places to avoid the heat” due to the recent extreme heat in summers around the world, and is proposing a new trip to spend a cool and comfortable summer at facilities located at high altitudes. It is generally said that the temperature drops by about 0.6℃ for every 100m increase in altitude. (*2) Among the facilities operated by Hoshino Resorts, we will introduce facilities where you can escape the summer heat and enjoy a cool vacation around the country, focusing on KAI Oku-Hida, HOSHINOYA Karuizawa, HOSHINOYA Fuji, and RISONARE Yatsugatake, which are all located at an altitude of 800m or more. *1 “Coolcation” is a coined word combining “cool” and “vacation” *2 According to the International Standard Atmosphere Background In recent years, the average summer temperature has risen throughout Japan, and the number of extremely hot days has been increasing. This summer (July to September) is expected to be higher than average nationwide, with the heat peaking from the end of July to the first half of August, and the heat is expected to linger from the second half of August to September. (*3) In light of this background, the need to “spend vacations in cool places” is increasing, and Hoshino Resorts is promoting the travel trend “coolcation” in Japan to meet this need, and proposing a cool trip. In “coolcation,” Hoshino Resorts focuses on “altitude,” and believes that facilities located at high altitudes are the perfect choice for escaping the summer heat and staying cool and comfortable. This summer, when it is hot, we propose a new resort stay option where you can not only stay indoors, but also feel cool at your travel destination. *3 Weathernews Inc., “Extreme Heat Outlook 2025” Recommended this summer!
