ANA Holiday Inn Resort Karuizawa, located in Kita-Karuizawa, Naganohara-machi, Agatsuma-gun, Gunma Prefecture, has launched a new early summer stay concept from April 2026, featuring nature experiences, outdoor activities, and resort dining against the backdrop of Mt. Asama. A period-limited All-inclusive Resort Stay plan — covering dinner, drinks, and a selection of activities — is offered through July 31, 2026.
Early Summer Nature Experiences in Kita-Karuizawa
Kita-Karuizawa transforms in early summer as the trees fill with vivid green foliage, creating an immersive highland atmosphere. With pleasant temperatures and clear air, the season is well suited for outdoor walks and sports, all set against the sweeping backdrop of Mt. Asama.
Active Experiences in the Highland
Forest Walks and Birdwatching
The forest paths around the resort come alive in early summer, when fresh greenery and cool highland breezes make for ideal walking conditions. This season also sees increased bird activity, including the possibility of spotting the hotel's mascot bird — the Japanese Blue Flycatcher (Ouruuri), known as a "bird that brings happiness." The bird's vivid blue plumage and melodic forest song are among the highlights of a walk in the area.
Binoculars are available to borrow at the hotel, making it easy for first-time birdwatchers to join in.
Putter Golf and Tennis
Putter golf and tennis are popular options for families and groups visiting the resort. The open outdoor setting, surrounded by greenery, offers a relaxed environment where guests of all ages and experience levels can enjoy some light activity.
Details on facility hours and fees are available on the official facilities page.
Indoor Pool
The resort's indoor pool features large windows that let in soft natural light, allowing guests to swim in a relaxed, nature-connected setting regardless of the weather. An adjacent indoor jacuzzi is also available, offering a way to unwind after a day of activities.
Nature Hills Karuizawa Country Club
The 18-hole golf course, which opened for the season on April 11, offers panoramic views of Mt. Asama and is designed to be accessible for beginners and women. In early summer, the highland climate provides a cool and comfortable setting for a round of golf as part of the resort stay.
Details are available on the official golf course website.
Natural Onsen "Aioi-no-Yu"
The resort's natural hot spring bath overlooks Mt. Asama, allowing guests to soak while enjoying filtered light through the trees and views of the surrounding landscape. The onsen bath changes character with each season.
Sauna
A wood-lined sauna is available for guests looking to relax and recharge. A mist sauna is also adjacent, providing a gentler steam option for those who prefer lower heat.
Foggi Forest Dining
The resort restaurant, Foggi Forest Dining (フォッジ・フォレスト・ダイニング), draws inspiration from the natural surroundings of Kita-Karuizawa, with a concept focused on locally sourced, seasonal ingredients. The buffet-style menu includes colorful starters using local vegetables, a Japanese and Western dinner buffet featuring dishes such as roast beef from Joshu beef, and a seasonal breakfast buffet each morning.
All-inclusive Resort Stay Plan
A limited-time All-inclusive Resort Stay plan is available from May 5 to July 31, 2026. The plan includes dinner with free-flow drinks (beer, wine, and more), as well as access to activities such as putter golf, tennis, and the indoor pool (subject to operating schedule). A late checkout until 2:00 PM is also included.
