As for when to go, the best time to see the stars is in the dry, crisp air of winter. However, they are also easily spotted in the summer, when the stable atmospheric conditions give rise to better visibility.

What Makes it the Best Starry Sky in Japan?

The secret lies in its natural environment. Achi Village is surrounded by the peaks of the central Japanese Alps. Moreover, the village covers a wide area of about 214, but is home to only 6,500 people. Therefore, compared to busier urban settlements, there is much less man-made light. The rich natural environment is also located deep in the mountains, so there are reduced levels of air pollution. The cumulative impact of all of these factors means that the sky above Achi Village shines brightest as "Japan's Most Beautiful Starry Sky".

Taking a Tour

There are two ways to get the most out of your visit to Achi Village. For those who are already used to astronomical expeditions, all that is necessary is to find the perfect spot on your own and begin gazing upward. For anyone looking to enjoy the stars without too much effort, a tour is recommended, like the "Paradise in the Sky: A Night Tour of the Best Starry Sky in Japan", which organized by "Star Village Achi". While of course offering the natural beauty of the night sky, this tour, which changes three times per year based on the seasons, offers a diverse range of other attractions, too. Running until March 31st, 2019, the "Winter Night Tour - Stars by Naked -" includes views of a star-filled night sky projection mapping on the grounds of the square at the mountain foot. From April 13th until October 21st, the "Heavenly Paradise - Japan's Best Starry Sky - Night Sky Tour" will be held, allowing you to climb 1,400m to the top of a mountain in a cable car where you can enjoy the night sky while listening to a guide.
If you wish to apply for one of these tours, tickets are available from 10:00 am exactly two weeks prior to your preferred tour date. It may be possible to book the tour from your accommodation or travel agent as well.

Tips for Stargazing

When venturing out to stargaze, it is important to prepare for the cold. As you would expect, it is important to wear appropriately warm clothing during the winter season, but it’s chillier than you would expect in the summer evenings, so make sure to pack a jacket or light sweater. Your neck may start to hurt if you’re gazing at the stars while seated, which is why it is recommended to prepare a sheet to place on the ground so that you can gaze at the stars laying down. You should also be sure to bring a small torch to light the area immediately in front of you, as viewing spots are located in pitch black areas.
