Night Life with the Stars
In 2006, the Ministry of the Environment named Achi Village the No. 1 area for stargazing in Japan. Anyone looking to immerse themselves in the Milky Way can do so at the area's main stargazing facility at Heaven Sonohara ski resort on top of Fujimidai Heights. Visitors can even enjoy stargazing while riding gondolas on the 2,500-meter (8,202-feet) -long ropeway to the 1,400-meter (4,593 feet) peak. There, at Star Village Achi, visitors will find a café, and a wide-open plain with telescopes to view stars and constellations in a pitch-black environment.
Star Village Achi hosts many guided stargazing tours. Prospective visitors can check the schedule and book tickets at the Star Village Achi website, or purchase as part of a special accommodation package with local hotels and inns (ryokans), some of which provide a shuttle service.
Namiai Park, which opened in 2018, is another facility in the mountains that offers stargazing parties at an elevation of 1,200 meters (3,937 feet).
When preparing to stargaze, it is important to remember that it will be chilly at higher altitudes, even during the summer, so dress appropriately. Better still, bring a blanket to help keep you warm while stargazing on your back. Remember to pack a small flashlight to light the ground area when looking for a place to settle down for the big show.
Seasonal Attractions & Excursions
While stargazing is the main attraction at night, Achi Village and the surrounding areas offer much to do during the day as well.
The Jibuzaka Highland is renowned for its beautiful flora. A plethora of beautiful flowers can be seen in full bloom from spring to fall. In spring, be sure to take in the scent of the Japanese azaleas. Approximately 10,000 peach blossoms – in red, white and pink – adorn Hanamomo Kaido Road for approximately 40 kilometers (24.85 miles) during end-April to early-May for the “Hanamomo (Peach Blossom) Festival”. In the fall, the broad-leaved trees of the forest turn various shades of red and yellow. It's like looking at a painting.
Take the Fujimidai Kogen Ropeway to Heavens Sonohara. Gondolas travel to an elevation of 1,400 meters (4,593 feet), offering magnificent panoramic views of the southern Alps. The area around the mountaintop station is paved, making it easy to enjoy a leisurely stroll. In early summer, around 10,000 skunk cabbages may be seen in bloom. In autumn, a tour in the early morning lets you enjoy a sea of clouds. In winter, the area attracts downhill skiers and snowboarders. Sledding and snowshoe courses are also available for visitors of all ages and experience levels.
For even more sightseeing in the area, the Central Alps Komagatake Ropeway provides sightseeing of Senjojiki Cirque , where glaciers carved steep slopes approximately 20,000 years ago.

Local Specialties and a Soak
The morning farmers' market in Achi is a popular source of locally grown products all year round. There are local fruits, mushrooms, dried persimmons and homemade jam, among other seasonal delicacies.
Soba (buckwheat noodles) is one of Nagano Prefecture's most famous delicacies. Visitors can take a class in soba making before dining at a restaurant to savor this local specialty.
No trip to Nagano Prefecture is complete without a soak at a local onsen hot spring resort or thermal spa, a few of which are available in Achi-mura. The Japanese have long thought that a hot spring soak cleanses both body and soul. The mineral-rich waters sooth and stimulate, relieving sore muscles while restoring one's energies. It's a perfect way to unwind after a day of sightseeing before heading out for stargazing.
