The night sky has captured people’s hearts, souls, and eyes for generations worldwide. The glittering stars, planets, celestial phenomena, and ever-present glow of the moon are deeply intertwined in humanity. Japan is no different and offers awe-inspiring destinations and activities that celebrate the beauty of the night sky.
Astrotourism is defined as travel that is centered on experiencing starry skies and celestial events, including stargazing and even traveling to witness an eclipse. With the threat of light pollution in our modern era, astrotourism is more important than ever as it not only builds awareness and appreciation for night’s allure but also creates economic incentives for communities to preserve their night skies.
In this comprehensive guide, we will introduce starry sky destinations, night tours, and celestial events across Japan.
Japan’s connection to the night sky
Japan’s relationship with astronomy is as rich as the cosmos themselves, blending science, mythology, and cultural values. Like most civilizations, the stars played a huge role in ancient times, helping Japanese people navigate, tell time, and even determine the optimal moment to harvest crops.
In addition to these logistical applications, the stars also greatly influenced Japanese folktales. For instance, Tanabata, an annual summer festival also known as the Star Festival, is about celestial lovers—represented by the stars Altair and Vega. According to legend, these celestial beings were separated by the Milky Way; however, on July 7 every year they are able to cross the divide and reunite.
Today, people celebrate the meeting of these two lovers by writing their wishes on colorful pieces of paper and hanging them on bamboo trees, as well as decorating their communities in vibrant streamers. One of Japan’s most famous Tanabata festivals takes place in Sendai, Miyagi Prefecture.
Another timeless Japanese tradition is tsukimi, or moon viewing. Held in autumn, this practice is dedicated to honoring the harvest moon, combining Shinto, agricultural, and artistic elements to create a meaningful celebration of gratitude and aesthetic appreciation. During tsukimi, people typically offer tsukimi dango (rice dumplings), seasonal fruits, taro, and chestnuts to the moon and display pampas grass to symbolize a good harvest.
While these examples are far from exhaustive, they illustrate how Japan and the night sky have long been intertwined.
Dark-Sky destinations in Japan
The International Dark-Sky Association is an organization that provides leadership, tools, and resources to individuals, policymakers, and industry, in order to reduce light pollution and promote responsible outdoor lighting. It is the globally recognized authority on night sky conservation and is responsible for certifying International Dark Sky Places (IDSP). These IDSPs are recognized for their efforts to preserve and protect the night sky, as well as promote education and implement responsible lighting policies.
As of March 2026, Japan is home to four IDSPs.
-
Kozushima (Tokyo): This remote island, resting about 170-180 km south of central Tokyo, was designated as a Dark Sky Island in 2020 thanks to its outstanding efforts to preserve the nocturnal environment. Full Earth—a company dedicated to connecting visitors with nature and promoting eco-friendly mindsets—offers a captivating “Star Watching Tour.” Led by a passionate local, this tour features a full-fledged astronomical telescope, as well as transportation to and from the selected stargazing spot.

-
Iriomote-Ishigaki National Park (Okinawa Prefecture): Iriomote-Ishigaki National Park is Japan’s southernmost national park and features the only tropical rainforest in the country—acting as a home for numerous threatened species. It was recognized as an International Dark Sky Park in 2018. Since tourism (including astrotourism) is a major source of revenue for the area, many local organizations have come together to promote responsible lighting policies and an appreciation for the night sky.
-
Minami-Rokuroshi, Ono City (Fukui Prefecture): Minami-Rokuroshi is a vibrant plateau located on the southwestern foothills of Mt. Kyogatake and is home to a plethora of wildlife and natural resources. The area was designated as an Urban Night Sky Place in 2023 thanks to Ono City’s policies against light pollution and its promotion of light pollution awareness. You can enjoy a stargazing program at Milk Studio Oku-Echizen, an open-air bath under the stars at Tron Hot Spa Urarakan, and impressive views through a telescope at the Fukui Nature Conservation Center.
Other notable stargazing destinations in Japan
In addition to the aforementioned IDSPs, Japan is home to a variety of areas where the night sky takes center stage.
In general, the best conditions for stargazing occur in winter when the air is clearest and during a new moon, when the sky is at its darkest. Equipment-wise, we recommend bringing:
- Binoculars
- A telescope (if applicable)
- A star app or chart
- A flashlight
- A camera or tripod
Also, remember to dress warmly as daytime and nighttime temperatures can differ drastically.

Can you see the Aurora Borealis in Japan?
In short, not really. It is possible to see the Aurora Borealis (Northern Lights) in Hokkaido and other parts of northern Japan, but the phenomenon is a faint red color, rather than green due to low altitude. Typically, the lights are difficult to see with the naked eye but can be visible in long-exposure photos as a reddish glow. Generally, sightings occur in late autumn or winter and require high intensity solar activity.
Celestial events in Japan
Japan plays host to a number of breathtaking celestial events, including comets, supermoons, planetary alignments, meteor showers, and lunar and solar eclipses. Below, we will outline the future dates of these phenomena, as well as the best places to witness them.
Lunar and solar eclipses
Lunar eclipses occur when the Earth moves between the sun and the moon, casting a shadow on the moon. Conversely, solar eclipses happen when the moon moves between the Earth and the sun, fully or partially blocking out the sun’s light. Total lunar eclipses color the moon in a rusty red hue—earning it the nickname, “blood moon.” While, a total solar eclipse appears as a black circle in the sky surrounded by the sun’s fiery light.
Let’s see when these special celestial moments are happening in Japan next. Please note that the peak times may differ depending on the viewing location.
| Event name | Date | Duration | Peak | Best viewing location (city) |
| Total lunar eclipse | Dec 31, 2028 / Jan 1, 2029 | 11:03pm–4:40am | 1:52am | Fukuoka, Kawasaki, Kitakyushu, Kyoto, Tokyo |
| Total lunar eclipse | Dec 21, 2029 | 4:42am–10:40am | 7:17am–7:24am | Fukuoka, Kitakyushu, Nagasaki, Sasebo, Tsushima |
| Annular solar eclipse | June 1, 2030 | 3:36pm–6:20pm | 4:55pm–4:57pm | Asahikawa, Date, Kushiro, Sapporo |
| Partial lunar eclipse | June 16, 2030 | 1:14am–5:52am | 3:33am | Fukuoka, Kawasaki, Kitakyushu, Kobe, Kyoto, Nagoya, Tokyo |
| Total solar eclipse | Sep 2, 2035 | 8:29am–12:23pm | 10:05am–10:08am | Nagano, Toyama, Utsunomiya |
Remember, in the case of a solar eclipse, it is extremely dangerous to look directly at the sun. Doing so can damage your eyes and even cause blindness. When observing a solar eclipse, you must wear eclipse glasses or view it through a solar filter. Ordinary sunglasses do NOT work. You can also view a solar eclipse indirectly through projection. The only time you can view a solar eclipse without protection is when the moon completely obscures the sun (totality).
Please review the eclipse safety guidelines in detail. Lunar eclipses are safe to observe with the naked eye. Check out Eclipses in Japan for more information.
Meteor showers
Meteor showers occur when the Earth passes through a trail of debris left behind by a comet or asteroid—casting shooting stars across the sky like sparkling “rain.” In Japan, you can view multiple meteor showers annually. In 2026, the meteor showers with the best viewing conditions are listed below.
| Meteor shower | Date (2026) | Peak | Conditions |
| Lyrids | Apr 16–25 | Apr 13 at 4am | Good: no moonlight; however, the peak occurs after twilight. |
| Perseids | Jul 17–Aug 24 | Aug 13 at 11am | Good: no moonlight; however, the peak is during the day. |
| Orionids | Oct 2–Nov 7 | Oct 22 at 3am | Good: no moonlight and peak is at night. |
| Geminids | Dec 4–17 | Dec 14 at 11pm | Good: little moonlight and peak is at night. |
Supermoons
Although not an official astronomical term, a supermoon happens when a full or new moon coincides with the moon’s closest approach to Earth, called its perigee, and generally only occurs a couple times a year. To the naked eye, a full supermoon will appear slightly larger and brighter than normal. It is an incredible sight to behold on a clear night. Listed below are the 2026–2028 supermoons.
| Year | Date |
| 2026 | January 3 November 24 December 24 |
| 2027 | January 22 February 20 |
| 2028 | January 12 February 11 March 11 April 9 |
Planetary alignments
A planetary alignment occurs when several planets appear to line up in the night sky. Types of planetary alignments include planetary conjunctions (when two planets appear very close), a “parade of planets” (when multiple planets follow a line), and an occultation (when one planet passes in front of a smaller one and blocks its view from earth—extremely rare). From your point on Earth, with your naked eye, the planets will look like bright stars “parading” across the sky. Learn more about planetary alignments.
| Type | Date (2026) | Visible planets | Best time to see |
| Small (4 planets) | Apr 18 | Saturn, Mars, Mercury, Neptune | Morning |
| Mini (3 planets) | Jun 12 | Mercury, Jupiter, Venus | Evening |
| Large (6 planets) | Aug 12 | Jupiter, Mercury, Mars, Uranus, Saturn, Neptune | Morning |
| Small (4 planets) | Nov 14 | Mercury, Venus, Mars, Jupiter | Morning |
Comets
Comets are small Solar System bodies made of frozen gases, rock, and dust that orbit the Sun. When the comet’s orbit brings it close to the sun, it heats up, forming a glowing head and tail. The comet’s head often appears green, while the tail is a blend of blue, yellow, and white. The sight is spellbinding. Listed below are comets that are expected to be visible in 2026. However, please note that it is difficult to precisely predict comets.
For your understanding, perihelion is the point in which a comet is closest to the sun. Also, the table below only lists comets visible in and information related to the Northern Hemisphere.
| Comet | Visible from Earth | Perihelion | Closest approach to Earth | Notes |
| C/2026 A1 (MAPS) | Late Mar–early Apr | Apr 4 | Apr 5 | The comet will likely remain low, just above the southwestern horizon at dusk. So, it will be harder to spot. However, it will pass extremely close to the sun, and if it does not disintegrate, it has the potential to be brighter than the full moon. |
| C/2025 R3 PanSTARRS | Late Apr–early May | Apr 19 | Apr 26 | You will be able to observe the comet before perihelion. Although it will be too dim for the naked eye, you will be able to see it with binoculars under dark skies. However, there is a chance it will brighten due to forward scattering (when dust in the comet’s tail refracts sunlight toward Earth). If this occurs, it could become the brightest comet of 2026. |
| 10P/Tempel 2 | Early Jul–late Aug | Aug 2 | Aug 3 | The comet will appear close to the horizon. Around perihelion, its brightness will be visible through binoculars or a small telescope under dark skies. |
